Description
G-Series diffusers suppress high-angle light above 65 degrees to reduce visual glare and improve the Unified Glare Rating (UGR) of luminaires. This helps luminaires comply with IESNA RP1-04 and EN12464 glare specifications. These patent-pending diffusers, unlike conventional prismatic sheets, have a soft cutoff with no color separation thereby increasing visual appeal and LED hiding ability.
Benefits
- G-Series diffusers can increase central (on-axis) candela intensity by up to 30%, or as high as 60% when used with a C-HE55 or CHE80 diffuser.
Features
- Glare Control
- Suppress high-angle light above 65 degrees
- Soft cutoff with no color separation
- Gain Diffuser
Recommended Uses
- Glare Control diffusers exhibit a variety of appearances depending on illumination conditions. They can be used in conjunction with C-Series diffusers to better hide light sources and further increase gain

Usage Notes:
• G-Series diffusers must be flat to achieve glare control; they can not be formed in curves around lamps
• G-Series diffusers must be used with the microstructure facing away from the LED or lamp
• Helps luminaries meet ANSI/IESNA RP-1-04 and EN12464 glare standards for office/indoor lighting
• Suppression of glare and efficiencies are typical; they vary greatly depending on luminaire design
• Bright View applications engineers can assist with product choices and help your design achieve peak performance
