Tuffak® LUMEN XT Sheet is a translucent polycarbonate
product with a textured surface on one side specifically
designed for lighting lenses. It features a unique combination of high
light diffusion and high light transmission through a combination of
optimized surface texture and advanced diffuser technologies.


When compared to other light diffusing products such as glass and
acrylic, Tuffak® Lumen XT Sheet has superior impact strength
and toughness. Its higher flammability resistance and wider service
temperature range provide an additional performance advantage over
acrylic diffusers.


The wide range of standard diffusion levels as well as both a warm
(LW) or a cool (LC) hue offers designers the flexibility to maximize light
fixtures’ aesthetics and performance. Other surface textures are available
for additional design options.


Applications for Tuffak® Lumen XT are Interior LED and
conventional lighting fixtures. Product is available in 1/16” and 1/8”
and carry Flammability rating of UL-94 V2.
