† Bend Radius values are at room temperature operation. Bend radius should increase as temperature increases. Contact Bright View application engineer for further information.

* UL Rating is for substrate material as provided by substrate vendor. Yellow cards for these substrates are available. Bright View diffusers have not been tested or rated by UL. Bright View applies a thin (approx. 50 micron) coating to these substrate materials. Please call a Bright View applications engineer to discuss your material needs.

Rigid Products

Bright View diffusers are available on a variety of materials, including film, semi-rigid, and rigid sheets to meet most lighting needs. Rigid sheet products are constructed by laminating a thin film to a rigid sheet.
