Suitable for variety of applications

Makrolon® DX Makrolon® Lumen XT

Different diffuser needs vs. fixture type Down Light

Wall Sconce Decorative – appearance (aesthetics) and luminance uniformity equally important

Recessed – direct glare not an issue

Non-recessed – glare from LEDs must be controlled by lens

Cove Light Decorative – appearance, illuminace uniformity, mixing of colors important

High Bay – industrial setting, on high vantage point Appearance not the primary consideration. Durability is important

Troffers – large area overhead lights Often desire luminance uniformity Light panels

Low Bay Different approaches – some value luminance uniformity, others want the highest transmission

November 2013 – Bayer MaterialScience Sheets, Global LED Segment

Edge-lit panels often require front diffusers to improve uniform luminance from edge-lit LGPs
