Dirty old river, must you keep rolling; Flowing into
the night… That’s the opening line to the Kink’s
“Waterloo Sunset,” as its composer, Dave Davies,
observed the world in 1967 from Waterloo Bridge
over the Thames in London. The bridge, FYI, is
near Waterloo Station, a destination I had some
diffi culty fi nding about a year ago when I was
in London to meet with UK lighting designers
Speirs and Major about a cool SSL product they
were helping develop with Cree—the Aeroblades
fi xtures we profi led in July.
Why am I musing about British bridges and
train stations, or lighting designers for that mat-
ter? Just the other day the lighting consultants
sent me a press release about a project involving
LED they’re doing at the city’s University of Arts.
It got me thinking about my trip, a year ago, and
the aforementioned tune popped in my head,
which in turn, triggered another memory from
a November past: Back in 2009, coming off the
second ArchLED conference, I relayed a story
from the old Rocky and Bullwinkle show about a
race between one of the fi rst steam locomotive
prototypes and a horse and buggy. The cartoon-
ish humor lied in the fact that while the train
was doing well against the horse, it crashed to
spectacular sound effects and explosive visual
symbols when it came through a tunnel that,
unfortunately, was completed only half way.
Later in the episode, after the train got going
again after overcoming the tunnel obstacle, the
cartoon’s protagonist, in approaching an upcom-
ing river chasm, asks the locomotive’s inventor
about foreseeable problems they might encounter
with the bridge. The inventor calmly notes that
it might indeed be an issue, as in this instance,
plans for the bridge were only 50% complete.
More spectacular sound effects and explosive
visual symbols…

So three years later, what’s the status on
that 50% tunnel and bridge? I observe the steam
engine—or LED engine—prototypes are almost
fully developed. That’s the good news, but much
of the track, tunnels and bridges remain unfi n-
ished as this technology continues to develop.
Not to despair, I have a notion I believe may
help, at least with the laying of infrastructure:
Like that Kinks song that keeps popping into
my head when I think of London, the power
of psychographics should not to be underesti-
mated. But the association that matters, in this
case, is connecting SSL with a powerful ally: the
zero-energy building movement. SSL, I believe,
needs something to differentiate it from the rest
of the crowd, and that differentiator is the fact
that SSL so neatly fi ts into the net-zero model.
Let’s begin with the critical net-zero tenet that
buildings should generate more power on their
own, independent of the grid. LED lighting, which
can operate on low-voltage DC-DC systems, as the
EMerge Alliance has so effectively demonstrated,
means LED fi xtures can directly be powered by a
photovoltaic source, even wind energy—providing
a direct, and achievable function for the rather
nebulous role alternative and renewable power
devices have to play in net-zero projects—at least
from the aspect of doing so without having to
construct giant wind farms or cover every sq. ft.
of one’s facility with solar panels.
Add to the equation its low energy consump-
tion, controllability, color tunability, long life
and modularity for future scalability—SSL is the
logical electric illumination source of net zero. So,
what I’m getting at is the SSL community must
work on developing a catchy Waterloo Sunset-like
melody, one that will bridge one with the other.
Of course, we must also get to work on fi nishing
that bridge design, and building it for that matter,
before we all end up in the drink.•

The 50% Bridge Revisited
Despite rapid product improvement, a great deal of supporting LED infrastructure remains to be laid. Perhaps it’s time to switch this train to the Net-Zero track.

ABOVE: The performance range was similar to LED Lighting Facts, and in general, the LED lamps had higher effi cacy
than both incandescent and CFL BR30/R30 lamps. The lumen output has increased over time; many lamps now match
the lumen output of 65- or 75-watt incandescent BR30/R30 lamps.
ABOVE: Excluding one product with very high effi cacy (91 lm/watt), the Series 16 products had luminous effi cacies between 51 and 65 lm/watt. This is favorable compared to other light source types commonly used in directional lamps, and should continue to rise.

Round 16 of DOE’s latest CALiPER testing focuses on directional BR30 and R30 Edison-base LED lamp retrofi ts. While this is a smaller category than the PAR lamp target, the use of the R and BR lamp is widespread in residential and cost-sensitive commercial spaces. The lamps tested are direct replacements for ineffi cient incandescent and CFL refl ector lamp products, where energy savings is the primary value added. The report reveals several signifi cant issues, most notably the disconnect between some LED products entering the market and market reality. In this case, while the LED products do duplicate the light output, and deliver energy savings, their high cost misses the mark for customers who choose “R” and “BR” lamps mainly due to their price. While some may purchase the lamps due to interest in LEDs, there are numerous “PAR” retrofi t products that will perform better at the same or lower initial cost. As far as testing results, for clarity, rather than lumping all directional sources into a single category, it is best considered when divided into two sub-categories: Semi-directional—products without focusing optics; and Focused-directional—products that produce a distinct directional emis-sion. The former include “R,” “ER” and “BR” lamps. The original form of these lamps utilizes internal silvering and a blown-glass envelope to produce hemispherical distributions. This classifi cation now includes CFL refl ector lamps. Focused directional sources, identifi ed as “MR” and “PAR” lamp forms, use molded-glass refl ectors with specular alumi-nized coating and glass lenses to produce high center beam energy and greater control. Round 16 focused exclusively on the LED products targeted as replacements to the lower performing BR30 and R30 semi-directional lamps. The application of these lamps includes recessed down-lighting,

directional display and accent lighting. as the overly broad light distri-bution is cut off by baffl es and fi xture bodies. Lacking a center beam focus, these lamps are frequently low performing in application.
Cost ConsiderationsA key consideration in R and BR lamps is that they are primarily chosen for fi rst-cost over performance. The LED versions tested in Round 16 range in price from $35 to $104 (mean $55.39), opposed to the incum-bent incandescent lamp cost of $2.80, or a CFL BR30 cost of $9.90. This raises the question of whether these products will be accepted in the highly cost-sensitive target market they are designed to satisfy. The lamps tested consumed between 6 and 14.3 watts, with a mean effi cacy of 59 lm. per watt—only slightly better than the CFL replace-ment benchmarks which tested at 39-51 lm. per watt. In comparing the CFL to an LED R or BR lamp with identical optical distribution, there is little to support the premium cost of the LED products in this category. Six of the 13 LED lamps tested produced distributions virtually identical to the CFL replacement it was being benchmarked against, while only one came near the slightly narrower incandescent bench-mark. This seems at odds with the application of the inherently directional LED light source, which is erased by use of diff users, which destroys any justifi cation of their high price premium beyond potentially longer service life.
Photometric PerformanceUltimately, how well a lamp performs in application falls on its pho-tometric performance. In this case, the majority of the tested LED replacements were apparently designed under the assumption that the CFL replacement R lamp was the desired target—which appears to be designed to replace the 65-watt BR lamp. However, four of the LED re-placements delivered greater optical control with slightly narrower beam patterns and moderately improved fi eld angle control. Compared to the other lamps, these products would produce improved performance in enclosed fi xture designs, representing a composite improvement in fi x-ture effi ciency. However, for the same price, a PAR30 LED replacement product with even greater optical control and directional energy could be obtained that will outperform all of the lamps tested in application. Round 16 illustrates the disconnect that exists between some LED products entering the market and actual market reality. In this case, while the LED products do duplicate the light output, and deliver energy savings, their high cost misses the mark for customers who choose “R” and “BR” lamps mainly due to their price. While some may purchase the lamps due to interest in LEDs, there are numerous “PAR” retrofi t products that will perform better at the same or lower initial cost. For this reason, one must question the need for this class of LED replace-ment lamps altogether.•

Combining a grid-based structure with a dazzling display of Mylar balloons and LED lighting arrays from Traxon Technologies, Cloudscape also served as a popular meeting place. Designers connected the company’s fl exible Dot XL and String RGB products to motion sensors to produce light shows that grew in intensity with the crowd’s movements below.

The project involved replacing CFL downlights and linear fl uorescent fi xtures with CR22 architectural troff ers from Cree. The new luminaires were installed in the building’s American Grill, sundry shop and main hallway, and should reduce related energy demand by 33%. Plus, the LEDs’ extended life should also help reduce maintenance requirements.•

solid-state lighting from philosophical to practical
perspectives, delivering unique perspective views
of the developing picture of solid-state technol-
ogy. These annual reviews offer an opportunity
to assemble a few thoughts colored by reader
comment, direct observation, review of project and
product submissions, input from lighting profes-
sionals, national lighting and energy organizations,
and competing trade journals. In any technology
moving as fast as solid-state, looking back is of
questionable value while taking a moment to look
into the light can provide insight into what might
emerge from the shadows.

Just a few years ago the most effi cient packaged

have given way to current LED device perfor-

exceeding 40W per device. The progress in LED
source performance in these raw terms has been
impressive. Additionally, as data comes in from
LM-80 testing, projected L70 service life is even
more exciting, with many LEDs now supporting
more than 70,000 hours of projected performance

room for newer innovators. In an ironic twist, one
of the most vocal proponents of LED displacement
of conventional manufacturers, Cree, purchased
Ruud lighting, a manufacturer of conventional
products as well as LED standout brand BetaLED.
The explosion of product and manufacturers
entering the market leads to speculation that this
is the boom that will lead to an inevitable bust.
While it may appear this is the case, SSL is still
a very young technology to the lighting market,
attaining less than 10% market share overall
to date (according to DOE reports). That means
there is plenty of opportunity to grow, even in a
crowded market space. Certainly, at some future
point there will be over-saturation leading to a
bust cycle. This is a self correcting feature of free
markets. However, there is no indication that
2012 is anywhere near this event horizon, so be
prepared for more expansion in the near term.
Of greater concern is the supply of LEDs
themselves. In 2012, shortages of substrate mate-
rials and phosphor supplies, plus limited inven-
tories due to obsolescence cycles, presented very
real obstacles to deployment efforts. If left uncor-
rected, this will put the brakes on market expan-
sion, regardless of demand growth. To answer
this, in 2012 many LED vendors shifted focus to

luminance volume has dropped signifi cantly.
Roadway and area luminaires once employ-
ing hundreds of LEDs are giving way to newer
approaches using less a fraction of that num-
ber. The result is more compact designs and
lower luminaire costs. High intensity sources
also increase optical effi ciency. However, the
downside to brighter LEDs is potential for glare,
and eye damaging intensity. IEC Standards
62471-2006 and ANSI/IES RP-27 have evolved to
address this issue directly, with test procedures
and exposure limits defi ned, including blue light
emission associated with white LED sources.
Use More Low and Mid Power, Lower Cost LEDs per LuminaireThe improvement in LED effi cacy applies to
products at all energy levels. This has given rise
to products utilizing low and mid-power LEDs
in tightly spaced arrays to deliver more uniform
luminous presence. This is made possible by the
low cost of the lesser LEDs. The end result is the
potential to create luminous surfaces without vis-
ible dots and spots, while thermal control issues
are reduced. This applies well to soft general light
sources and linear strips, where individual LED
visibility detracts from visual appearance.
PRODUCT AVAILABILITYBetween 2010 and 2012, there has been an explo-
sion in available SSL product. Conventional and
new entry SSL manufacturers have increased the
number of introduced offerings of SSL products
signifi cantly. This is refl ected in the listings at
Lighting Facts, which has ballooned from a few
hundred to thousands—as has the number of
Energy Star products available. Lightfair and
Light+Build were overwhelming in their array of
LED products, components, sources, replacement
lamps, and supporting controls. The growing
demand from customers to for LED products, and
building customers asking for LED alternatives in
lighting decision making is driving manufacturers
to accelerate product development efforts.
Most noteworthy is the mix of new and
incumbent players, with no signs of LED induced
attrition. This is counter to the assertion that the
transition to solid-state would create a wholesale
washout of conventional manufacturers to make

metrics. While the discussion of CQS continues
in the CIE, CRI remains the only established
standard for defi ning color quality. The longer
this process takes to be resolved, the more costly
it will be for manufacturers to re-test or recalcu-
late products and update literature and web sites.
Because of this, and a seemingly soft demand
from the market to address this, there is no pro-
jected end to this issue in sight.
WINNING HEARTS AND MINDSOf all areas of weakness in the current deploy-
ment approach to solid-state lighting, there
remains a persistence to apply the technology
within the myopic focus on energy savings
through retrofi tting the Edison socket inventory,
and directly displacing conventional products
with like SSL products. Because of this, many of
the greatest successes in SSL deployment are
hidden from view. By pursuing a one-for-one
replacement strategy—which is the easiest from
a marketing and sales perspective—spotting a
solid-state application requires a trained eye to
see where they actually are. Some contend that
this is desirable, as it removes any negative reac-
tion, similar to that CFL experienced. However,
this dilution of visibility conceals the technology,
which makes all the hype seem out of proportion
to observable reality.
Further, every effort to make SSL products
mimic conventional sources assumes the conven-
tional is more desirable to all new alternatives
where SSL can shine as a superior choice.
In the consumer market, this is aggravated
by big box retailers displaying LED products
alongside CFL sold at a fraction the price, on
shelves shared with familiar incandescent prod-
ucts even lower in cost.
As has been stated in this publication
many times, dismissing approaches to employ
solid-state to improve visual performance, and
superior aesthetics creates a price disadvantage
to LED technology that will take several more
years to overcome. With a few exceptions, as of
2012 solid-state lighting remains short of enticing
customers to see it as a “must-have” value. When
a T8 or T5 fl uorescent lamp costing a few dollars

STANDARDS DEVELOPMENT2012 was a slower year for rolling out new
standards than has been experienced in the
period from 2008 to 2011. While several com-
mittees made progress on topics of color, fl icker,
and safety, the most notable standards progress
occurred with the launch of the Energy Star
Luminaire section, and the fi rst of Zhaga Consor-
tium module release. Another related release
was by the Federal Trade Commission, who put in
place their Lighting Facts labeling requirements
effective January 2012. This differs from the DOE
Lighting Facts program, which is voluntary. The
FTC requirements are mandatory on SSL replace-
ment lamps sold through consumer outlets. The
slower pace of new standards released is a good
sign, as it indicates most of the larger issues of
testing and communication of color, life, per-
formance, and power consumption have been
addressed.

the installed cost, in a non-modular, replace-the-

a preferred option. The most compelling cases
for SSL is for replacement of halogen MR, R and

to replace poor performing CFL and ineffi cient
halogen products, and street/roadway/parking
application to eliminate the maintenance costs
and energy consumption of HID lamps.
There are exceptions to the replacement
strategy showing growing favor in 2012. Linear
LED products, from thin cabinet mounts, display
cases and refrigerated cases, to line voltage
exterior products have seen widespread success.
These products deliver value through tunability
of in light output and optics, in a modular format
well suited to cove, display, accent and wash
applications. Further, lower profi les, hardier envi-
ronmental enclosures, long life and low energy
use add up to advantages that have energized
this category of SSL product. Color LED effects
also remain a solid value-adding proposition.

steadily while performance continues to improve.
Further, color consistency in LED devices has
advanced dramatically with improved binning
and production controls, as well as new technolo-
gies in the application and composition of phos-
phors employed. The proliferation of greater-
than 90CRI LEDs in desirable CCT colors has also
expanded appreciably.
Another signifi cant area of improvement
in 2012 has been the availability of LED prod-
ucts able to operate effectively on conventional
controls (dimmers). Several products now offer
full range dimming from Triac controls. This,
alongside advancements in dimming availability
overall, development of wireless technologies,
and intuitive intelligent controls is putting LED a
step up on conventional products.
OLED AND PLASMA SOURCES2012 saw the introduction of several OLED
products. The most notable were from Acuity
(see above), which presented several innovative
designs using the new technology to create light
forms of distinct and unique character.
While cost, availability, color and life issues
remain concerns, 2012 was a turning point for
OLED from being a lab concept to a viable candi-
date to step into the realm of the practical.

Advancements in Plasma light sources also
saw improvement in 2012. Now available in 90+
CRI and colors more appropriate to broad lighting
use, plasma presents a signifi cant improvement
in optical control and compact source archi-
tecture that HID and LED are unable to equal.
While limited in real utility to applications where
greater than 10,000 lumens are needed, such as
open area, roadway interchange, large fl ood, and
sports lighting, plasma is an excellent companion
to LED technology.
A COMPLEX VISION - CONCLUSIONPerhaps the most noteworthy development of
2012 was that advancements occurred in many
areas, from the technology to improvements in
the market itself. The raw proliferation of solid-
sate products is a signifi cant and needed stage
for the technology to move from slow to rapid
advancement.
With a larger number of players compet-
ing for customer attention, innovation will shift
from simplistic metrics and low-hanging fruit, to
delivery of greater value-added offerings.
While there are many manufacturers offer-
ing solid-state products concentrated on large-
volume segment opportunities. This is an obvious
marketing ploy, and sells well to non-lighting
investors who respond to big numbers over
esoteric design values. This has begun to shift
in 2012 as privately owned and conventional
manufacturers who know the inner workings of
lighting have become more active. The result is
an emergence of new product designs of unique
and special character. From lighting that changes
color in response to its dimming state, wireless
roadway lighting that communicates condition
states to a central database, lighting controls that
harvest their own power for operation, and BIM
integration, solid-state lighting is maturing in
both sophistication as well as price and perfor-
mance.
If 2010 was a tipping point of attention
toward SSL, 2012 marks the beginning of true
transformation. There are a few more hurdles to
be overcome. However, the next four will be when
solid-state becomes the source of choice for all
but a few segments of lighting.•
GREAT NEW PRODUCTSA number of LED products are beginning to diff erenti-
ate themselves from the pack, taking advantage of SSL's
unique properties. For example, Philips' Ledalite introduced
its TruGroove luminaire, a sleek, recessed LED fi xture that
fi ts unobtrusively into the ceiling providing a value archi-
tects have clamored for, for years .

A MATURING INDUSTRYLED manufacturers are beginning to take a very diff erent
approach to marketing their products. For example, Holo-
phane is putting its money where its mouth is, so to speak,
in the creation of its night time interactive demo, where
customers are able to walk through a series of outdoor il-
luminated environments at their Granville, Ohio campus, to
experience, fi rst hand, the quality of diff erent LED sources.

Retail stores are opening and

not typically seen in the headlines
of the mainstream business press,
but original research for Architec-

2. Energy-use restrictions
have made retail owners consider
not only energy costs to light their
stores, but what lighting does to
enhance the sales appeal of prod-
ucts on display.
3. Retail lighting presents
today’s lighting practitioners the
opportunity to utilize the palette
of lighting options as an applied
art form in the built environ-
ment, enhancing everyday living
experiences.
The Arrow is Pointing Up
The scope of activity of the retail
store design and construction
market is still growing. As the
industry is moving into its high-
grossing fourth quarter, U.S. retail
industry sales have already risen
to $2.57 trillion, up 3.5% year-to-
date. “Pent-up demand is turning
desires into needs, which is one
reason why consumers have begun
opening up their wallets,” says NRF
chief economist Jack Kleinhenz.
Other observers predict a
year-end increase of up to 4.5%,
citing a strong back-to-school
season. Retailers are closely track-
ing factors such as unemployment,
election results, and inventory
levels that could throw a wrench in
holiday results.
Jerry Storch, Toys R Us chair-
man and CEO, also dismisses the
notion that stores like his are a
dying breed to be replaced by Inter-
net-only giants. He put the cost of
“Direct-to-Home” e-commerce 1.5×
to 2× higher than that of the classic
method of shipping inventory to
stores where customers purchase
items and take them home.
Still, in other countries and
income levels, retail’s current vol-
ume is spotty. Sales are down 19%
in Australia, and up just 1.8% in the
U.K. At the top end of the market,
however, most luxury labels are
tallying strong numbers. Prada,
which in the past year opened 28
stores in countries such as Brazil,
Morocco and the Ukraine, acknowl-
edges the effects of political
troubles on the southern shores of
the Mediterranean, but according
to CEO Patrick Bertelli, signs for
these problems have been evident
for years. Prada experienced a 60%
leap in total volume for the current
fi scal period.
Stephen I. Sadove, CEO of
Saks Inc., is also concerned about
the global economic situation,
elections, and the fi scal situation.
“But we feel confi dent about the
long-term health of luxury, about
growth in the sector and the oppor-
tunities that are out there.”

The Forces Of Retail
The global economy is a force moving retailers and wholesal-ers to expand scope and reach to increase market share, revenue and customer base. Investment in employees, prod-uct design, new store openings, and marketing are paying off for retailers who are expanding their international presence in order to become less depen-dent upon a local, regional or national economy. That said, the U.S. is still considered a mecca for retailers seeking an international presence in a stable marketplace. Advances in technology are another force transforming retailing itself as well as the shopping experience. Respond-ing to increasing customer de-mands, retailers are giving local, national and global customers access to merchandise, service, and product information, tai-lored to their requests. Many retailers and whole-salers are also being smarter about their real estate, opening smaller stores, minimizing their footprint while increasing their sales-to-square foot ratio. Designers and manufactur-ers with a desire to tell their own brand story and infl uence the customer experience are increasingly becoming retailers, creating an upscale environ-ment for their luxury and aspirational products. These signifi cant trends, growing in momentum in the U.S. and internationally, are the drivers that signify that retail is undergoing global transforma-tion, prompting predictions that within fi ve years the current business model will be nearly unrecognizable.

Vitrashop Group, Birsfelden, Swit-

most likely to accept sustainability
as a strategy if tangible results are
apparent. “Some of the key aspects
are energy-effi cient lighting,
thermally insulated glazing, and
state-of-the-art air conditioning
technologies that save energy.”
Additionally, a growing num-
ber of retail decision-makers, he
indicates, are asking suppliers how
their products are made, and how
the products can be safely disposed
of. The store design industry is cer-
tainly in the "awareness" phase as
far as sustainability is concerned.
Rapid progress is being made in
areas where energy consumption—
and thus costs—can be reduced
measurably, for lighting, and in
food retail, for refrigeration and

think-tank, EHI, found that 25% of
energy costs in the food retail sec-
tor go toward lighting, and in the
non-food section, lighting accounts
for up to 75% of energy costs.
“Against a background of rising
energy prices," EHI attests, "there's
a renewed focus on more effi cient
lighting, including LED."
In concert, big box and
department stores are shrinking
the footprints of new stores, while
shuttering older outlets, and reduc-
ing the size of existing outlets. For
example, Neiman Marcus, with
stores typically in the 200,000-sq.-
ft. category, is monitoring the
success of its recently opened
87,000-sq.-ft. store in Walnut Creek,
California. Similarly, Staples is
cutting the size of 30 of its U.S.
stores—1% of its U.S. total. Wal-
Mart, too, is embracing this trend,
opening fi ve Neighborhood Market
stores in California’s Central Valley,
ranging in size from 31,000 to

of this smaller-sized format to 200

Catering to the Shoe Lover
Perhaps one item that's recession-
proof at a global level is shoes.
Shoes have become the high-prof-
itable, fast-turnover darling of the
retail industry, at all price points.
“The footwear market was the last
to feel the pain of the recession and

the company’s mission to unlock
the emotional kick consumers get
every time they buy a new pair,”
says Cook.
Last year, DSW sold 30 million
pairs of shoes in their 344 stores.
Architect David Schwing, head of
the retail store design studio at
BAR Architects, San Francisco, has
designed several DSW stores, and
notes lighting plays a critical role.
“A customer will feel comfortable
in the store, understand product
and color choices, and read product
information and sizing easily only
if lighting levels accurately portray
the materials and colors,” says
Schwing.
“Foot Jewelry” is how interna-
tional store design consultant Ken
Nisch categorizes today’s consumer
attitude toward footwear. “Shoes,
along with eyewear, are where the
excitement is at retail now,” says
architect Nisch, CEO of JGA, South-
fi eld, Mich. “From casual to athletic
to dress, shoes have evolved into
an important accessory,” Nisch
observes in his advice to clients
worldwide on merchandise presen-
tation strategy. “Attractive lighting
on full length mirrors is part of the
art of selling footwear,” he says.

merchandise in today’s hyper-

solutions devised by lighting
designers can motivate purchasing
at all price points.

objective was to impart a premium

Primark. “The distinctive curved
end of the ‘ship-shape’ plan is
illuminated externally with LEDs to
create a grid of light at night that

lighting level is low, with a reliance
on directional rather than ambient
sources to create a more intimate

Beyond more traditional applica-
tion, retail lighting for exterior
and interior retail spaces can
demonstrate elegant and original
integrated interpretations that
are both artistic and functional. A
prime example is the Wintergar-
den Shopping Centre in Brisbane,
Australia, which has three street
frontages that are a complex
expression of nature, geometry,
layering and illumination. Designed
by Melbourne-based Studio 505
architects, the lighting feature

Breuninger's major shoe depart-
ment is by a light artist. World-
class architects like David Adjaye,
who did Proenza Schouler, are
being commissioned to design for
retail, and they understand the
expertise of someone like Paul
Gregory who did the lighting. It
wasn't always the case, but today
retail lighting is as much of a cre-
ative challenge as is any segment
of the building and construction
industry, and far bigger.
The extraordinary increase
in the amount of stores being
launched or renovated in the past
two years offers business opportu-
nities for design professionals of a
like of which has never been seen.
Finally, the attention to
energy use restrictions is making
retail owners think seriously—not
only about the amount of energy
that lighting accounts for and what
it costs—but what the lighting looks
like on the sales fl oor and what it
does for the products on display.
Just the sampling of designs
featured, shows the great deal of
creativity on the part of designers
and manufacturers to understand
the role of lighting in motivating
retail purchasing, across price
points. Clearly, retail lighting is at
the forefront of practical applica-
tions of augmenting the light-

attention to lighting in the built
environment around the world as
part of enhancing everyday living

The Challenge:Like many older gaming facilities, the Coeur d’Alene Tribal Resort, located near the town of Worley in the northern portion of the Idaho panhandle, was in need of expansion. The casino’s manage-ment was faced with the task of adding something new in order to compete as a true destination, with attractions for non-gamers, and to increase its overall appeal. The goal of the tribe was to cre-ate a complete resort experience, integrating elements and sym-bols of their tribal culture and beautiful natural landscape with modern design trends and light-ing technology. The challenge, therefore, was to create a dra-matic new facility with improved amenities while respecting the tribe’s concern about their impact on the environment.
The Solution:The result is a 110,000-sq.-ft, LEED Gold-certifi ed addition comprised of 100 four-star guest rooms, two restaurants, a lounge, a spa, and the “skycatcher,” a circulation element that connects the new elements of the complex with the existing gaming space and provides a gathering space with sweeping views of the roll-ing hills of the Idaho landscape.

Vision Quest
When it came to approaching
how to illuminate the expansion
and renovation of the Coeur
d’Alene resort, which included an
existing casino, lighting designer
Jill Cody had a specifi c vision:
It would not be Las Vegas-style
glitz, rather, she wanted to inte-
grate the lighting as an addi-
tional layer to help tell the tribal
story and enhance the warmth
usually associated with hospital-
ity settings in a way that harmo-
nized with the rustic elegance of

the materials used. “This meant
the careful illumination of mate-
rials and surfaces, the creation
of contrast to enhance the mood,
and respect and reference to
tribal culture and tradition,” says
Cody.
Since the resort sits 30
miles outside of the eponymous
northern Idaho town, there is no
light pollution in the night skies,
allowing lighting to subtly create
the resort’s environment.
“We were trying to create
an exciting environment, yet not
overwhelm the darkness. We
did not light the exteriors of the
buildings, but went for subtle
light from the interior rather
than Las Vegas-style sparkle,”
says the designer.
For example, bridging the old
building to the new is a courtyard
dubbed the Night Sky Lounge
(above). To spice it up, a blue
acrylic wall, that masks a wall on
the old building, is backlit with
LED puck lights placed randomly
for the effect of a starlit night
with softly twinkling stars. A

blackened and pre-rusted steel.
“It is a very Northwestern ma-
terials palette,” explains Cody,
who wanted to make sure the
materials got their due through
the lighting.
She decided LED RGB was
the appropriate medium for story
telling. “We used color-changing
for three major design elements:
Eagle Staff Tower, the Feather
Bench, and the Skycatcher fl oor.
Color sequences were created
with references to tribal culture,
such as costumes, the night sky,
“It makes you feel as if you are
doing this for a reason, and
makes it amazingly meaningful.
You feel connected to your work
as a lighting designer at the end
of a very long project.”
Color Correction
Color changing was also a big
part of the project as Cody
wanted to match up with archi-
tect Mithun’s choice of building
materials, which she says has
rural overtones, with an empha-
sis on wood, water and stone, plus
and Lake Coeur d’Alene, itself,
the tribe’s ancestral home. These
three color-changing elements
are coordinated with one another
and run on a schedule that tells a
different story each night of the
week,” notes Cody.
The elements are coordi-
nated with the same color at the
same time, which according to
Cody, took complex program-
ming to achieve, with different
palettes to evoke different tribal
references, from the color of their
costumes to a rainbow effect.
ELEMENTALWater is a critical element to the
tribe, as they once lived along the
shores of Lake Coeur d’Alene. The
resin waterfall is backlit with blue
LED to emphasize the element
of water. In fact, the winding
luminous line points directly to
the lake.
THE RIGHT TONENatural colors and elements, in-
cluding wood, were also important
components within the project. In
the facility’s new restaurant, The
Steakhouse, lighting designer Jill
Cody noted there was a particular
emphasis to get the coloration
of the wood right in the dining
establishment.

Eagle Staff Tower
One of the most visible tribal-
inspired elements is Eagle
Staff Tower, a 105-ft.-tall iconic
column of Corten pre-rusted
steel with slots, or lens-covered
openings, that allow the color-
changing light to shine through
as a welcome beacon at night (its
base is visible in the upper right
background of the image to the
right). Each slot can be a differ-
ent color via signage-grade LEDs.
Red beads that adorn the tower
are lit from wells in the ground.
The Water Feature
Approaching the entry to the
resort, a winding, luminous resin
water feature guides guests to
the resort’s front door. Linear
LED fi xtures backlight the resin
and highlight a Corten steel wall
that runs behind the water.
“The tribe used to have land
on Lake Coeur d’Alene, and water
is very important to them,” says
Cody. “The line of light on the
water feature points to the lake.”
In fact, the light shines
through a transparent blue resin
material, using Hydrel fi xtures.
The water is also lit from the
front as well with Boca Flasher
linear submersible LED fi xtures
that reveal the movement of the
water. The light on the water fea-
ture is all white; as Cody points
out, “because the resin is blue,
there is no reason to change
colors on it. I really like the blue
against the rusted color of the
Corten steel.”
The Steakhouse
In the new restaurant, The
Steakhouse, Cody used LED
fi xtures where appropriate, as
well as dimmed incandescent
lamps to meet a one-footcandle
light level.
“The color quality of the
light was really important with
all the wood in the space,” notes
Cody, who used MR16 downlights
on low-voltage tracks in the ceil-
TRANSITIONDaylight is a prominent element
coming into the facility, particu-
larly its “Skycatcher” area. The
casino, however, is much darker
and a transition had to be created
to link the two and create way-
fi nding for casino patrons.
MATCH ON ACTION In the entry there is also an art
installation with abstract time-
lapse photos of tribal members in
traditional costumes. The images
are on laminated glass with a
sandwiched fi lm layer. “The idea
was to take tribal stories and
weave them into the project in
unique ways,” says Cody. “It was
a real education for the design
team; we learned a lot about the
tribe and their history.” Colored
LED was employed in the fl oor
to evoke the legend of “Coyote
Scratches” and match up with the
colors in the art feature.
ing. During the day, a large glass
wall allows a lot of natural light
to enter the space, and low light
levels near the glass minimize
refl ections and allow a clear view
to native plantings outside.
“There is a different quality
to the light during the day,” Cody
adds, noting that the lighting
in the restaurant is actually
bumped up during the day to
make sure the back corner of the
room seems brighter, and to bal-
ance the room.
She also used Winona linear
LED kick-lights and LumenPulse
cove lighting to add accents to
the wood ceiling.
The Casino Entry
The theme of color-changing
light continues at the casino
entry, creating a transition zone
between the bright, day-lit area
of the “skycatcher “and the much
darker gaming fl oor.
In the “skycatcher”area (be-
low, left), a blend ceramic metal
halide uplight and downlight
creates quiet gathering zones to
balance a more active circulation
zone. Uplights and downlights
are turned off during the day in
this well-daylit space.
But in this space, LED
comes alive in communicating
another tribal reference: the
legend of “Coyote Scratches” in
the landscape, which are evoked
in the space with glowing LED
tiles (Lightwild) that reach out
into the “skycatcher” to hint at
the excitement inside the casino.
“We wanted to tell people that
something existed back there,”
says Cody.

In the entry there is also
an art installation with abstract
time-lapse photos of tribal mem-
bers in traditional costumes.
The images are on laminated
glass with a sandwiched fi lm
layer. “The idea was to take tribal
stories and weave them into the
project in unique ways. It was
a real education for the design
team; we learned a lot about the
tribe and their history,” Cody
notes.
The Spa
Adding to the allure of the resort
is a spa where the design is
defi ned by a large stone wall,
uplit with incandescent sources,
which Cody selected for “good
dimming control,” although she
adds it is “unusual” to use incan-
descent on a project at this scale
these days.
The downlighting is a mix
of MR16 and fl uorescent. “We
started designing this project
in 2009. There is a wider choice
of LED fi xtures to choose from
today, but I’m not sure we could
have afforded them for almost
1,000 downlights on this project.
The spa also features a glass
panel that sits atop the stone
wall, allowing light to splash into
the adjoining pool, once again
emphasizing the importance of
daylighting in this project.
The Courtyards
Beyond the centerpiece blue
wall, another signature design
element in one of the outdoor
courtyards is a wooden bench
evoking a feather.
CONNECTED TO THE LAND The tribe carries a deep connec-
tion to the land and the resort
site sits at the confl uence of two
habitat types: grassy hills and a
forest. As a result, exterior views
were important to the architec-
ture. Low light levels near the
glass minimize refl ections and
interior lighting is warm and quiet
to impart an ambiance of refl ec-
tion and healing.

LEDs under the the feather
bench give it the appearance of
fl oating on a cloud of light.
“The bench is designed like
an eagle feather, another impor-
tant element of tribal culture,”
says Cody. “The Corten center of
the feather is illuminated with
linear Lightwild white light that
does not change.“
All colored light at the bench
changes at the same time, so the
experience is different from the
tower and Skycatcher, where
multiple colors are visible at a
given time.
“Instead, the sequence of
color takes place over time,” says
Cody.•

TRIPLE AXEL LANDED: SUSTAINABILITY AT A REASONABLE COST& IMPROVED LIGHTING

ABOVE: The retrofit dropped wattage consumed by about 40 watts per sq. ft., which cut the office’s total lighting consumption in half. Between energy savings and maintenance savings, the company will save about $1 million annually. A mix of sources were employed, almost a quarter of those being LED. “We didn’t set out to do an LED retrofit, it just evolved that way,” says Lighting designer Stephen Margulies of One Lux Studio.

The professional services firm of Ernst &
Young believes in corporate sustainability.
In fact, the organization hopes to have half it’s
employees in LEED-certified spaces by 2013. But
being accountants, they want to make sure any
such measures reflect financial soundness. A
recent, significantly LED lighting retrofit of the
company’s Manhattan offices proved a fruitful
marriage of both goals—oh with a third benefit of
greatly improving the lighting environment.
As part of their sustainability initiatives,
the company regularly consults energy special-
ist Jim Schwartz of JAS Consulting to keep tabs
on their buildings with an eye toward better
efficiencies where and when possible. In the
course of such due diligence, about three years
ago, Schwartz had a casual conversation about
the company’s Times Square offices with lighting
designer Stephen Margulies of One Lux Studio.
As Ernst & Young was preparing to enter a
new lease on the space they wished to evaluate
a few things, particularly lighting. Following a
walkthrough of the 32 floors of offices, Schwartz
knew “instantly” that “millions of watts” could
be pulled out of the space. That being said, the
consultants also wished to be sensitive to the
original lighting design created by Gensler and
Susan Brady, which was done about 10 years
prior. At the time, the emphasis on the lighting
design was more on the aesthetic, according to
Margulies, and the design was indeed “fantastic,”
but not so efficient from an energy perspective.
“There were lots of MR-16s and lots of mainte-
nance issues,” says the lighting designer.
Not only were there a lot of inefficient
sources—many with old ballasts—but the offices
were generally overlit. In some places they found
light levels as high as 80 footcandles. “We started

This was of great relief to Margulies as
he wished to drop light levels by almost half
in many spaces. Another aspect the designer
is particularly proud of is the fact that all the
retrofitted lamps were UL certified—something
that surprised Ernst & Young’s insurance carrier.
According to Margulies, this due diligence was
important to the design team to not only ensure
safety, but make sure that warranties would not
be voided. This was especially significant as the
project was being delivered turnkey by Philips
Lightolier Energy Service Group, who was not
only supplying product, but providing financing
and a 5-year warranty on all of the products.
As a result of the retrofit, maintenance
costs dropped from $16,500 annually to $3,000.
Combined with the energy savings, this yields a
3.5-year payback. “It all goes back to cost benefit,”
says Margulies.
Philips, who has a long-term relationship
with Ernst & Young, took on the project as it fits
well with their corporate philosophy. CEO of the
Lighting Division, Zia Efeketar notes Philips saw
the project as great example of the “triple axis”
that needs to intersect: the ability to meet sus-
tainability goals; improved energy efficiency at a
reasonable cost; and improved lighting quality.
thinking this was more than a light bulb change,”
says Margulies. The goal became to reduce the
overall power density from roughly 200 watts
per sq. ft., to as low as they dared dream.
That said, both he and Schwartz wanted to
preserve as much of the original design as pos-
sible, including retaining as many of the existing
fixtures as possible. And because of the technol-
ogy available today, notably LED, the pair felt
confident this was not only achievable, but that
they could maintain, even improve the quality of
the lighting environment, particularly in private
offices. “You can’t underestimate lighting qual-
ity,” says Margulies. “We took the non-daylight
spaces and made them great.”
Where possible, the consultants simply
replaced source for source. Where not possible,
the team refitted existing fixtures with new
sources. In some cases, new fixtures were cre-
ated. The team proceeded with mock ups, many
with much lower light levels. To get feedback,
they actually had Ernst & Young employees
evaluate and comment upon the look and feel of
the space.
“I remember it was a rainy Saturday, and
many of them didn’t even notice any difference,
which we took as a compliment,” says Schwartz.
How about first cost? Efeketar says the
project was viewed by the client as an invest-
ment. “So from the beginning, ROI was on the
table and we had to figure out what the payback
had to be—to make that happen, we had to go
with an integrated system,” says Efeketar.
This was an important decision for Ernst
& Young—or any client—as moving away from
decisions based completely on initial cost, to one
that’s a calculation of total cost of ownership,
forces the client to establish “X” return from
the beginning, so the team knows exactly what
needs to be done, and at what cost. “The ultimate
goal is reaching that ROI,” says Efeketar.
Will this project have a domino effect? “The
train has left the station,” says Efeketar. “I feel it
will be a positive endorsement, especially for a
public auditor of its stature. It certainly begs the
question: Why not you [other corporate entities]?”
Regardless, Efeketar says the foundation
for such retrofits has been laid, and it’s a solid
platform, granted the sums must add up.
“There are clearly economic uncertainties
to overcome. That’s where we’re hoping our
internal financing will help,” says Efeketar. “But
if you can’t achieve payback in a period of 18
months to five years, it’s not a proposition.”•
SMOOTH TRANSITIONThe new lighting system reduces annual lighting energy consumption by 54%. More than 3,000 high-wattage CFLs and MR16s were replaced with 20-watt LEDs. Elsewhere, existing fixtures were refit with LED components for greater ef-ficiency. In all, the lighting consultants “touched” nearly 20,000 fixtures—a fourth of that with LED solutions.
THE CHALLENGE:Pull as many watts as feasible out of the client’s
650,000-sq.-ft., nearly 6,000-employee offi ce space
while preserving as much of the space’s original
lighting design as possible.
THE SOLUTION:Three strategies were emploed:
• More effi cient retrofi t lamp sources were
installed where possible—notably among the
existing MR16 and CFL lamps
• As many existing fi xture/luminaires were
retained as possible, but refi t with more effi cient
light source components
• Replace fi xtures where necessary to
accommodate more effi cient sources
As a result, the design cut lighting consumption in half from its whopping original 6.2 million kWh per year, simultaneously reducing CO2 emissions by roughly 2 million pounds.
THE CHALLENGE:Pull as many watts as feasible out of the client’s
650,000-sq.-ft., nearly 6,000-employee offi ce space
while preserving as much of the space’s original
lighting design as possible.

wide objet ’d’art. A winner of Cooper’s Source
Award earlier this year, the spectacularly illumi-
nated structure resides, where else, but in the
Land of Lights, Las Vegas, where the bar’s draw
is an experience that bathes guests in crystal-
lized light.
Upon entering the hotel’s casino, opulent
strands of crystals drip dramatically from the
ceiling; their luxurious luster beckons gamblers
to pay a visit to one of the fi ve bars and lounges
that are seemingly suspended inside the crystal-
line strands.
The lighting design team from New York-
based Focus Lighting, along with architect the
Rockwell Group, created the unmistakable
illusion of a single internally lit chandelier,
and supplements it with lighting techniques to
achieve sparkle in every delicate strand. With
technical expertise and a larger-than-life mock-
up, the team deliberately aimed light at each of
the kinetic chandelier’s seven million crystals.
Their research helped to predict the precise
angle at which each crystal would need to be il-
luminated to achieve the maximum sparkle with
minimum headaches—that is, provide a dramatic
display that is neither nauseating nor glaring to
the casino’s guests.
Being nearly 50-ft. high, the chandelier is
surrounded by a concourse or casino circula-
tion on two levels. It also contains fi ve separate
bars and lounges that seem to hover within the
ethereal space.

ETHEREAL BEAUTYThrough a combination of color motion and controlled sparkle, guests are able to experience vastly different moods as the chandelier transitions from day to night. The three-story core features 700 crisp, white dimmable LEDs mounted within a sparkling liquor tower and spiral glass stairs, creating a strong contrast to colors on the crystal swags.
multi-head fi xtures are installed vertically in the

multiple points of warm, beautiful front light.
Each lighting position was studied in plan and
section and then mocked-up on site to review
precise aiming angles.
A dimmer switch and controls program
transitions the chandelier from daytime to a
night-time lighting scene that intensifi es the
drama throughout the evening hours. As part
of the evening program, light, color washes and
abstract images are projected onto the vertical
crystal drapes, which are supplemented by an
additional layer of vinyl-coated aircraft wire.
Stairway to Heaven?
You’ve heard of a champagne fountain, but how
about a liquor chandelier? A solid light source
runs through the core of the bar (above), which
includes the staircase used to circulate through-
out the three fl oors of the casino. The three-
story illuminated inner core features 700 crisp
white dimmable LEDs mounted within a spar-
kling glass tower that acts as a liquor display
surrounded by a spiraling glass staircase.
Don’t Mock the Mock
A year prior to the chandelier’s erection, Gregory
and the Focus team constructed a full-size, 20-ft.
tall mockup of an entire section of the chan-
delier. The mockup allowed the design team to
analyze the appearance of the lighting on the
crystal from both the outside and inside of the
chandelier. Furthermore, the mockup provided
the opportunity for adjustments in factors such
as lamp type, color, and fi xture positions and
quantities. For example, the effort allowed the
Focus design team to determine that there was a
need for an additional layer of halogen uplights.
It also provided them a substantive mechanism
to demonstrate to the client, that there, indeed,
was a need for 150 of the Lumiere 203s.
For those guests who enjoy an intimate
drink with the barkeep, several softly illumi-
nated enclaves provide a cozy atmosphere with
halogen downlights to give warmth, while a
custom chandelier reinforces the theme.
Visionaries?
Like everything in Vegas, the over-the-top
crystal distraction would have guests feeling like
Alice in Wonderland, but for the expert vision of
Focus Lighting, which has made it into a fi rst-
class spectacle.•

When a new technology emerges, there is a need for an extraordinary
educational effort to create viable customers for it. Since customers
experience technology progressively over time, the demand for
advancing education grows to serve a broadening range of need from
fundamental basics to focused specialty information. Whether
provided as a presentation at a conference, offered on a YouTube
video, or included in sales presentations, there are many opportunities
to participate in building customer knowledge. However, there are a
few fundamental rules that need to be adhered to that separate actual
customer education from simplistic company promotional efforts:
1) Know the Audience
Educational content that has no target audience in mind often
educates no one. Keeping the audience in mind provides guidance
as to what needs to be included, and at what level. If you don’t know
the customer, seek assistance from someone who does. Keep in mind
that the customer is an expert within their own universe, critical of
outsider error that reduces credibility. For example, failing to present
color and uniformity performance metrics as a higher priority than
pure energy saving to interior designers is a failure to understand the
daily demands made on this customer.
2) Present Information Objectively
Objectivity is the difference between promotional marketing presenta-
tions and actual education. Even when educational efforts are pursued
as part of a marketing program, erasing company bias when delivering
information is critical, even if some points in that content are counter
to company messaging. Objectivity includes presenting advantages
and implications of approaches, without distortion. For example,
presenting AC LED light sources as a favorable approach, based solely
on elimination of electronic components without covering fl ickerissues
and possible impact on effi ciency, is a failure to present objectively.
Further, educational programs designed to fi ll space, or masquerade
product presentations as “educational” fail the objectivity test.
3) Provide Contrasting Views or Approaches Positively
One of the most powerful tools for an educator is to present a problem
with several contrasting solutions. The depth of information presented
adds to intrigue and engages the recipients to think about the topic in
greater depth. For example, presenting a review of LED retrofi t lamps
to prove the inferiority of halogen lamps is less valuable than case
studies showing direct comparison of LED and conventional products
applied to lighting restaurants, covering the pros and cons of each.
4) Simplify the Scope and Expand the Detail
There is a measurable difference in value delivered between attempts
to cover a wide range of topics in shallow strokes and focusing on a
few specifi c items in greater depth. That does not mean expanding
complexity by delivering scientifi c data, it means tailoring the
information presented in context to the customer’s needs with depth
of information applicable to making practical decisions.
For example, retail lighting customers really don’t need to know—or
care about—the specifi cs of semi-conductor production yields, but do
need to know how LED color impacts appearance of products
displayed.

5) Lead Recipients through the Topic in Steps
Educational programs should be formatted in a linear, step-by-step
progression. This includes the briefest possible summary of basic infor-
mation, building more and more depth as the program is completed.
The balance of depth of information delivered at each step is an art
that requires careful planning and review. For example, presenting the
basics of human color perception and sensitivity, leading to a summary
of the issues of color metrics used for light sources, provides a progres-
sion of information that builds relevant understanding.
Evolve, Refresh
As technologies grow in familiarity, so do the needs of educational
support. While the very earliest phases of deployment demands basic
technical education, more mature customers will fi nd this content
redundant. This evolution of need provides many opportunities to
remain engaged in education by evolving new content. The key to
successful educational effort is to continually create fresh materials
to meet the growing needs of customers. The reward for participat-
ing as an educator, especially when approached with an objective eye
on customer needs, is growth of understanding in the market as a
whole. In the end, educated customers are more likely to take a risk on
an emerging technology, earlier, than those who are left confused by
marketing noise alone. •
THE WHITE PAGES
Over the past decade, LED lighting technology has continued to evolve
to meet the demands of today’s commercial market, providing users
with high-quality illumination, superior energy effi ciency, lower opera-
tional costs, lower maintenance costs and long service life.
As LED dies and packages continue to evolve, LED luminaires have
improved as well, which has led to a signifi cant increase in adoption
by engineers, architects and lighting designers. However, little has
been done by manufacturers of luminaires to maximize the benefi ts
of this improved technology. Specifi cally, the approach to fi xture and
optical design has not been modifi ed to take full advantage of the new
properties that exist with LED sources. As a result, there are still many
untapped benefi ts to LED lighting that can provide new options and
opportunities for lighting specifi ers.
Hyperbola: A New Approach for a Directional Source
Traditional light sources such as incandescent, CFL and HID lamps are
omni-directional sources, producing light in all directions. In order to
redirect the light down and out of the aperture of a recessed fi xture, a
parabolic refl ector is the most effective shape to maximize effi ciency.
However, due to the uni-directional nature of LED sources, utilizing
parabolic refl ectors has proven diffi cult in terms of minimizing glare
and achieving a uniform beam spread on the work plane. As a result,
additional diffusion is typically required when using a parabolic
refl ector in order to spread the light to achieve the uniform distribu-
tion that lighting designers and commercial building architects desire.
Prompted by the demand for low-glare, high-effi ciency LED
luminaires, engineers conducted extensive research and testing,
and discovered that changing the overall shape of the refl ector from
parabolic to hyperbolic provides superior light distribution control for
LED sources. Why? The inherent nature of the hyperbolic shape itself,
which refl ects and spreads light similar to a convex lens—as opposed
to focusing the light—is the reason.
Due to the geometry of the hyperbolic curve, there is no source
image in the refl ector as any refl ected light is directed down toward
the target work plane. By eliminating the need to diffuse the light with
a lens and redirecting the light toward the work plane, the effi cacy of
the luminaire can increase as much as 35%.
In addition, the hyperbolic surface allows the refl ector to block
the light that would be incident on the lower portion of the refl ector,
casting a shadow that dramatically reduces the aperture brightness.
The hyperbolic refl ector shape also reduces the amount of light-source
regression required for glare control by increasing the shielding angle,
thereby reducing the profi le of the downlight housing and permitting it
to fi t in a wide variety of commercial construction applications where
lighting designers are seeking a more natural lighting atmosphere. It
also allows for a more "silent" ceiling, a new architectural buzz word
referring to a simpler ceiling plane, where fi xtures in a space are not
as noticeable or conspicuous.
While parabolic refl ectors are still a high-quality option to
optimize light distribution in commercial applications that require a
more traditional appearance, the newer hyperbolic shapes allow
designers, architects and facilities managers more versatility and
control over the illumination characteristics of an application.
In addition to virtually glare-free, “silent” ceiling effect the
hyperbolic shape provides in commercial spaces, the unique curvature
also produces additional benefi ts to users such as:
• Increased lumens: The hyperbolic shape provides up to 35%
more lumens by directing all light at the target work plane
and eliminating the need for additional diffusing.
• Higher effi cacy: Up to 35% more lumens per watt.
• Increased application fl exibility: Increased lumens to
accommodate higher ceiling heights and better control of
the light allow multiple beam spreads.
• Unique aesthetics: Extremely low brightness
• Very large lumen packages from very small, and silent,
apertures
A New Option for Recessed LED Illumination
With the continued innovation of LED sources and the discovery of the
benefi ts a hyperbolic refl ector can provide in commercial applications,
lighting designers, architects and building owners now have another
option to consider when looking to create the ideal, aesthetic and
energy effi cient environment for building occupants. •

LETTERS TO THE EDITOR:RGB OVER THE EDGE, BUT DOESN’T HAVE TO BE
Just read your LED Insights [from the September issue] and can’t agree more. RGB, since becoming “leading edge,” has gone to “over the edge” in usage. It is often just plain misused in too many applications. That said, we are presently involved in using color changeable LED in a major residential pool and grotto system. In carefully mixing white, and control of the RGB, we, hopefully, will create pools with beautiful effects presently not known. The waterfalls are intentionally always left white so that there is no chance that own-ers can turn the “scene” into visual chaos. I am excited to see intense red water with white falls and white star effects randomly placed in the bottom of the lazy river along with fiber optic delivered LED white lights randomly placed in the ceiling of a rough stone ceiling. Rather than being a “starry sky,” they are to emulate the tiny eyes of unknown underground creatures. So, RGB, if planned well, can be good.

EDITORIAL PREVIEW:IN THE JANUARY ISSUE: We take a look at how SSL is being applied in office environments as general ambi-ent lighting. We’ll stick with our focus on interiors, with a profile on lobby/atrium of the Kansas City Marriott by Bruce Yarnell. Kevin Willmorth addresses proprietary controls issues associated with dimming LED. On the project front, we’ll showcase cool white lighting using exotic fixtures in the Sagafredo Cafe In Greenwich Village, New York. Across the Atlantic, we go inside a storage tank for a truly inspirational retrofit and re-use project. Also, new products, and of course, news.

ABOUT THE AUTHOR:
Kevin Willmorth, a lighting expert and fi xture designer,
has been instrumental in helping create a vision and
mission statement for Architectural SSL.
Let us observe a moment to refl ect on the light of the tungsten register has put upon us: Soon there will be a time when we have only memories of its warm yellow, color-distorting, and energy-hogging glow. So long old friend.

Requiem for theTungsten Resister Light
We have come to a turning point in lighting
where solid-state is poised to displace a tech-
nology we have all come to love—the tungsten
resister light, better known as the incandescent
and halogen lamp. While there remains a strong
bond to these heat sources masquerading as light
sources, the writing is on the wall. The use of
tungsten resistance technology is facing attack
by a superior technology armed to take it down,
and it’s got a silly name, and that is LED.
If only there was a way to make halogen
lamp much more effi cient and long lived. These
simple lamps asked only to be fed a fl ow of cur-
rent, AC or DC, modulated or not, and they lit up
gladly for their brief, power-thirsty life. They
could stand most any environment, hot or cold,
dim with the cheapest dimmers available and
generate a nice warm color, as long as they were
not knocked around. They also have the dignity
to just burn out when they are done with life, the
clearest indication of maintenance need.
Comparatively, LEDs are fussy about the
power you feed them, complain when over-
heated and are easily killed when mis-wired. The
slow death by lumen depreciation is just more
whimpering. And, what’s with all that electronic
gadgetry?—The entourage is unbecoming.
Halogen lamps have existed as long as they
have because they were relevant in compari-
son to other light sources available until just
recently. Fluorescent lamps are bulky and ugly,
impossible to control optically and require big
support gear. HID, Induction and CFL are awful
technologies, period. They are inelegant, hard
to design around, and generate barely tolerable
light qualities. One uses them because of practi-
cal reasons, not because they are great products.
If the world were lighted by tungsten resisters,
the earth would now be covered in a foot deep
layer of spent lamps, the economy destroyed, and
the atmosphere choked with the emissions of
millions of coal fi re plants.
Alas, LEDs bring with them the asset of tiny
kernels of light, halogen’s most precious feature.
Yet LED brings with it fewer liabilities, and an
arsenal of new values beyond the reach of the
obsolete. They deliver scalable light and form,
new optical potential and inherent directionality
coupled to a dizzying array of colors—delivered
with the kill shot of long life and energy
effi ciency. The only comfort one might capture
from the demise of such a loyal friend is that
tungsten resister sources are but the lowest of
hanging fruit. On the branches above are the
CFL, then HID, and linear fl uorescent. They can
hide for some time, but will eventually be pruned
to niche applications beyond the interest or
reach of the coming solid-state swarm. High
power LED, plasma, OLED, and sources yet to
be released from sequestration by non-disclo-
sure agreements, indicate a future essentially
absent of tungsten resisters.
Many will not miss fl uorescent lamps
when they are gone and most can’t wait to
see CFL killed off altogether. The eventual
absence of HID will not cause a second thought
to anyone. However, we will always miss the
simplicity of the halogen lamp. Even though
each individual lamp’s existence is more but a
fl ashbulb on the time line of lighting history,
the technology brought many of us great joy.
For tungsten resister lovers everywhere,
solace can be taken from the fact that LED
intrusion is being slowed by short-sighted
marketers and metrics engineers, who have
yet to discover the secret path to deliver the
true value of solid-state, which will be the fatal
blow—much like the smart phone ended to
popularity of the Princess phone, and digital
imagery devastated the instant camera. For,
as long as the LED is delivered in ways that
remind us of how much we love the tungsten
light source, we will never truly wean our-
selves from its magic embrace.•
