NeariNg artificial light to suNlight

The effecT of LighT

Why We need natural light

According to the evolution theory, mankind has developed under sunlight. Sunlight is

therefore completely natural and we feel well in it. Lack of sunlight may lead to general

weakening and may support various conditions. A czech proverb says ‘A sunny day

keeps the doctor away’. 120 years ago most people used to work under open sky. on

the contrary, today we spend most of the day in buildings under artificial light. The quality

of artificial light, which can be defined as its similarity to sunlight therefore becomes

important.

light and darkness

The darkness as a counterpart to light is equally important. only in darkness the

melatonin, the sleep hormone, rises to regenerate our body, scavenge free radicals and

remove cells that run out of control. it is therefore important that we are not disturbed

by light at night. Neither the light itself, nor the darkness alone, but the rotation of these

polarities is what keeps us alive.

effect of light on health

The sight is one of the pathways light affects us. Scientists (p. 5) have been investigating

the effects of light on our nervous system and hormones since 1950’s. The major

breakthrough came only in 2007 when a new photoreceptor has been discovered on

human retina: the photosensitive ganglion cells. These are neighbours to rods and cones,

but their function is not visual. They project to central nervous system the information

whether it is a day or night. Biological master clock, located in our brains under the

crossing of optic nerves get synchronized by light and it measures our circadian

(approximately a day-long) rhythm of alertness and sleep. The photosensitive ganglion

cells are mainly sensitive to blue light and when there is enough of it, they signalize

the brain it’s a day, time to be alert and active. NASLi light approaches sunlight in this

manner as well.

Mall-illuMination

The illumination under open sky at noon can be 20-100 thousand lux. The illumination

in interiors is often hundreds to thousands of lux. This is just one per cent! Need for light

is growing as one is getting older. A pensioner needs about fifteen times more light than

a child for the same task. Activating effect of light on nervous system largely depends on

the blue component. Warm white contains about one third of blue compared to sunlight.

People are often disappointed with the quality of light of compact fluorescent lamps that

replaced the banned incandescent bulbs. NASLi provides much better colour rendering.

What light is the best

The ideal light is of course the sunlight. Artificial light may approach sunlight from different

points of view, for example in intensity, in tone similar to some phase of the day or in

rendering of colours. it is advisable to use more intense, colder light for work and less

intense, warmer light for rest. Before going to sleep, dim warm light resembling sunset,

containing minimum amount of the activating blue can be recommended.

Prof. fritz hollwich (*1909 - †1991)was a german ophthalmologist, professor of ophthalmology and a director of ophthalmological clinic.

he worked in Munich, Jena and Münster. in his inaugural dissertation form 1948 he distinguishes

a visual and energetic path of the sight apparatus. Three quarters of total light are considered to have the

energetic function and only one quarter to have a visual function. The energetic function is demonstrated

by observing the levels of hormones and other substances in the body. Blind patients who regained

sight after cataract operation helped him to demonstrate how vitality is enhanced and substances

are returning to their natural levels when light can strike retina again. Prof. hollwich observed stress

hormone levels decrease in his patients after he had daylight fluorescent tubes installed in his waiting

room. in this way he contributed to a better light in hospitals.

he is an author of many medical methods, more than two hundreds specialized publications and of

many books. There are ten or more editions of his Textbook of ophthalmology, which is even after sixty

years still considered to be one of the cornerstones of modern ophthalmology. Prof. hollwich cofounded

international ophthalmological Academy. in his works, he also refers to John ott, a pioneer of better

artificial light. from the work of prof. hollwich one can feel truthfulness, scientific verity, german

precision and courage to present things the way they are.

dr. John ott (*1909 - †2000)was an American camera man and self-learned scientist. While working on the time lapse pictures for

Walt Disney‘s Secrets of life series he found that some of the plants do not blossom and finally fade under

warm fluorescent light. Step by step he discovered that artificial light that lacks some colour can have

adverse effect on plants and animals. Large importance is given to the blue light, which is weak in warm

white light. ultraviolet light, which normally does not pass window or spectacles glass is also considered

important. Dr. ott demonstrated that a light more similar to daylight can soothe school kids, but also prison

inmates. in this way he demonstrated how different kinds of light affect our hormonal system that,

in the end, controls our body and our feelings. Dr. ott was the first to talk about mallillumination.

he is a founder of Time Lapse Research foundation, Bio ecological Research institute and ott Lite

company, which is one of the first producers of fluorescent tubes with rare-earth elements that enrich

the spectrum of the light produced, enhancing the colour experience.

Dr. ott published several books, several tens of articles, made several thousands of lectures. in 1957,

he was awarded a title of honorary doctor of natural sciences by Loyola university of chicago. John ott

is an example of great enthusiast, unlimited by school indoctrinations, a pioneer of better illumination

who gained respect of both laic and scientific public.

dr. franz halberg (*1919)

was a Romanian scientist living in uSA, founder of chronobiology, the science of time order in the living

realm. he coined the term circadian rhythm. Member of the german Leibniz society, five titles as

Dr. honoris causa.

Prof. helena illnerová (*1937),

czech biologist and physiologist, priority in discovery in melatonin secretion is controlled by brain’s

biological clock. ex-chairman of Academy of Sciences of czech Republic and the Learned society.

chairman of czech uNeSco commission.

Prof. russell grant foster (*1959), British neurobiologist and flunder of photosensitive ganglion cells on human retina. one year after this

discovery elected fellow of the Royal Society.

dr. norman e. rosenthal (*1950)is a Southafrican psychiatrist living in uSA. in 1984 he published an article on seasonal affective

disorder (SAD) and it‘s healing by phototherapy. Dr. Rosenthal is an author or coauthor of more than

two hundred specialized articles. he published four books: Winter Blues, The emotional Revolution,

St. John‘s Wort and how to Beat Jet Lag.

dr. Jacob liberman (*1947),is an American ophthalmologist and author of Light - medicine of the future and Take off your glasses

and See. he is an inventor of the eyePoRT eye training device and system.

schools

The standard prescribes Ra ≥ 90 for art classrooms in art schools.

Dr. John ott found pupils being able to concentrate better, and

for a longer time, under fullspectrum lighting. Better visibility of

colours makes the classwork colourful and more interesting and

thus more efficient. The cold tone of light brings an uplifting feeling

of daylight.

kindergartens / nursery school

According to observations of John ott, children are more calm

and stay focused to a particular activity for a longer time under

fullspectrum lighting, this also applies to restless and hyperactive

children. vibrant colours are more likely to grasp the children‘s

interest.

households

Research papers from around the world, as well as our own

research and long term experience with our customers confirm

the activating effect of fullspectrum lighting to human biorhythms.

These natural daily cycles can be supported with the proper timing

of the right light, but they can also be disrupted by improper light

at an improper timing. fullspectrum light makes it easier to get

up and wake up in the morning. it also keeps us alert and active

during the day. on the contrary, in the evening it is better to

switch this activating light off and use only dim warm light about

60 minutes before going to sleep. This has a similar effect to

sunset: our rhythms will attune to relax, rest and regenerative sleep.

healthcare - treatMent rooMs

and surgeries

The standard prescribes lighting with Ra ≥ 90 for treatment rooms,

operating rooms and other healthcare venues. Diagnostics of

certain conditions largely depends on the staff ability to distinguish

colours, eg. yellow in jaundice and the lack of redness in hypoxia.

under general fluorescent lamp light (Ra 80) these colours may

be difficult or even impossible to distinguish. fullspectrum is a

synonym for high colour resolution.

healthcare - other rooMs

ongoing research shows cardiac patients feel much better,

recover faster and sleep deeper if they are exposed to an extra

portion of light during the day, compared to the general standard.

Best results are observed when blue-rich daylight-like light is

used. The experiments of prof. hollwich and Dr. Wurtman show

a decrease of the stress hormone in patients after fullspectrum

lighting has been installed in the waiting rooms.

APPLicATioN exAMPLeS

dentistry and dental laboratory

The standard prescribes lighting with Ra ≥ 90 for dentistries.

Tcp ≥ 6000 k is an additional requirement for dental laboratories. The

dentist needs to distinguish not only the colours of tissues, liquids

and tooth, but also the colours of various indicators and supportive

materials. implant colour has to be selected in a way that it would

mimic the neighbouring tooth colour in daylight. When the choice is

made under artificial light, this must be closer to sunlight, as much

as possible, so the patient would be satisfied with the result.

care/nursing hoMes

According to recent research, it is possible to enhance the quality

of life for the elderly and, at the same time, lower the expenses

on medication and night service, provided that the occupants are

subjected to intense blue-rich light during the day. People are more

lively and self-sufficient during the day, more likely to find joy in

some activity and get more tired, and finally sleep better at night.

artists and art restorers

Sunlight is an ideal light to judge matching colours, however, it is

not available all the time and in the required place. if general artificial

light was used for colour matching, the restorer could easily make

restorative colour appear matching, however, daylight would reveal

the difference. fullspectrum lighting is a great choice for colour

matching.

night-shift

During work at night, it is vital that workers keep alert during the

whole workshift. Blue-rich fullspectrum light activates the human

nervous system, thus keeping us alert and more active. it has been

proven that more intensive cold light can lower error rate, accident

rate, combat absenteeism and increase productivity even in daytime

hours. fullspectrum lighting provides better perception of colours,

making the surroundings more pleasant and vivid.

quality control checkPoints

Quality control, checking colour proofs in multicoloured print,

sensory evaluation in industrial varnishing or the evaluation of

colours of different materials or chemical indicators are largely

dependant on the proper distinguishing between colours. Again,

sunlight is an ideal light, but it is not available every time and

everywhere. The standard prescribes artificial light with high verity

of colour rendering, which is offered also by fullspectrum lighting.

Sice 2006, we record and process experience of our customers and cooperating companies. We ask new users of the NASLi lighting to fill in their

notions in a questionary to find out what changes did the they notice after the NASLi sources have been installed. The objective of this research is to

find out how people subjectively perceive healthy light. Typical answerers are employees of middle or large companies that decided to try the NASLi

lighting in some of their offices, classes, on their production floors or similar venues. We lend our light sources to companies for the time of the research

under certain conditions.

We encourage everyone interested in trying the products of healthy Light to follow the following

procedure that has been verified by many and leads to satisfactory results. We recommend starting

with little changes to provide enough time to get used to the new light. it would be a pity to install an

expensive luminaire just because it was bought without consideration. The need for light varies with

seasons the year and different living things need different light during the day. Need for light is also

affected by age, children need less light than the elderly.

We at NASLi provide professional consultation and design of interior lighting in offices, households

and production floors with focus on colour quality and circadian activation.

Please visit www.nasli.net to find out more.

A great improvement can be as simple as changing a fluorescent lamp, installing a kitchen lamp or

using a stronger bulb on the toilet or lavatory. A living room can get more life with a new desk or floor

lamp. We perceive up to 90 % of information by sight. comfortable illumination is therefore followed

by safety, alertness, productivity and quality of workmanship as well as wellness and vitality.

The level of illumination can be measured using a lightmeter. in this way we can check whether

the light is strong enough for the given task. There is no standard for household lighting, but

recommendations can be found in literature and eN 12464-1 standard can be used as inspiration.

* Maintained illuminance: When the actual illumination falls under this level, maintenance is to be performed: replacement of the light source, clearing of the luminaire etc. initial illuminance with new luminaires/lamps is ~50 % higher. cold light is pleasant at hundreds lux and more while warm light is pleasant under a few hundreds lux.

fullspectrum sunshine simulator helps to overcome seasonal affective disorder (SAD), depressions

induced by lack o sunlight, feelings of anxiety, lack of energy, fatigue, mood swings or decreased

performance.

fullspectrum sunshine simulator is easy to use. Just spend 15 to 30 minutes with the luminaire in

your visual field, about 1 meter distance. it is not required to stare into the light, you can comfortably

read, enjoy your hobby or work with a computer.

NuBeS luminaires are designed for minimum electromagnetic trace. New generation electronic

gear provides optimized current waveforms and low electromagnetic emissions. Lamps are

connected to the ballast with shortest possible route and the interconnection pattern is symetic and

additional filters are used to minimize electromagnetic interference. These luminaires can be used

as a stationary sunshine simulator.

how to overcome winter depression – SAD and winter blues (book in czech) provides one of the

most complete collections of information about SAD so far published in czech language. Readers

will find how SAD occurs, who is likely to experience it, what are the symptoms and how it can be

treated using light teraphy or other efficient methods and much more.

Many of the luminaires are shipped with intelligent

ballasts, that allow two different wattage lamps to

be installed in the same luminaire (Stella, gaudium

and some Pompa types). T5-ho high output

lamps, can be exchanged for T5-he high efficiency

lamps with lower power and lower luminous flux.

in this way, you can choose the most beneficial

configuration, keeping in mind efficiency and

maintained illumination at the same time.

Luminaire design is a creative process of seeking the balance between technical, functional and

esthetical sides of the product. Besides the classical technical parameters, we in NASLi work with

activating effects of light on human nervous system. Works of professor hollwich, a discoverer of

the association between quality of light and stress, have been a great inspiration for us in NASLi.

This is why we are nearing artificial light to sunlight.

These are special fullspectrum pendant luminaires for medical, dental,

veterinary, laboratory and similar workplaces. Thanks to an electronic

ballast, the light is flicker-free and more eye-friendly than classical

lamps using magnetic ballasts with a starter. The high colour rendering

index ensures true undistorted colours, as well as a better resolution

of fine detail, so you will feel much less eye fatigue after a whole day‘s

work. The optical systems used ensure a good even illumination of the

work area, with minimum glare.

LiNeAR fLuoReSceNT LAMPS

The work of prof. hollwich (p. 5), eminent ophthalmologist, confirms both biological importance of

fullspectrum light as well as essential nature of certain colours and results of their deficiency in everyday life.

cool white fluorescent lamps with poor colour rendering were banned in germany thanks to his research.

Personal experience is the best way to understand the difference of NASLi light.

Mercury in fluorescent lamp is a source of concern and questions. Mercury is liquid at room temperature

and it evaporates, contaminating the air. The vapour of this heavy metal is dangerous and neurotoxic.

A fluorescent lamp contains about 1/100 of the mercury contained in a medical thermometer. As the lamp

is sealed, the vapour is locked in the tube. Proper recycling is vital so the lamp mercury is never released

to air. in case of lamp break: open the windows and vent the room for at least 15 minutes. keep outside

the room during this period.

amalgam (an alloy of mercury with one or more metals)

makes dosing of mercury to lamps more precise, easier

and safer. Amalgams make controlled evaporation

of mercury during lamp operation possible. in case of

amalgam lamp break, the amount of mercury released

to air is much lower than in lamps with liquid mercury.

Mercury does not evaporate from amalgam at room

temperature. Amalgam lamps need more time to reach

full luminous flux and they may experience difficulties

while starting at low temperatures.

Torches, candles, paraffin lamps, gas lights,

incandescent bulbs, fluorescent lamps, arc lamps,

LeDs… the sources of light are constantly

developing, while their goal stays the same: to imitate

sunlight in place and time where it is not available.

fluorescent lamps and especially LeDs make bring

a new way of nearing to sunlight: not only the intensity,

but also the chromaticity can change during the day,

as inspired by sun on sky. This live – biodynamic –

light brings a motivating variable element to static

interiors while respecting our day cycle more closely

than any constant light.

Special phosphors with rare earth elements (lanthanides) are used in nasli fluorescent lamps. A Mixture of

these compounds emits light across the whole visible range, producing a rich white light that contains every

colour. for the sake of acceptable decreases in efficacy we get light that enables us to distinguish small colour

nuances, much like that in daylight. This is not possible under mainstream fluorescent lamps.

Lamps with excellent colour rendering (Ra ≥ 90) are required by eN 12464-1 standard for a long list of venues

and visual tasks in healthcare, dentistry, dental laboratories, art schools, print industry and quality control stati-

ons. our customers report great experience with our products in offices, schools, kindergartens, nursing houses,

photographic and art studios, DTP stations, fine mechanics and electronics workplaces, chemical and biological

laboratories. colour enthusiasts use NASLi lamps at home as well.

The lamps conform to all requirements on safety and performance, eRP and RohS directives and can be used

in existing luminaires without any modifications. T8 lamps can be used with electronic or magnetic ballasts.

electronic ballasts are preferable as lamps last longer, consume less energy and eliminate flicker, being more

comfortable on the eyes.
