Down Light
Makrolon® DX
Makrolon®
Lumen XT Suitable for variety of applications Different diffuser needs vs. fixture type
High Bay – industrial setting, on high vantage point
Low Bay
Wall Sconce
Cove Light
Troffers – large area overhead lights Often desire luminance uniformity
Non-recessed – glare from LEDs must be controlled by lens
Recessed – direct glare not an issue
Appearance not the primary consideration. Durability is important
Different approaches – some value luminance uniformity, others want the highest transmission
Decorative – appearance (aesthetics) and luminance uniformity equally important
Decorative – appearance, illuminace uniformity, mixing of colors important
Light panels
Edge-lit panels often require front diffusers to improve uniform luminance from edge-lit LGPs
