Glare control using Eclipse technology is designed to reduce glare. By integrating the light filtering element—our Eclipse technology—directly into the diffuser film, this new solution maintains high light transmission and a sharp cutoff angle while directing light axially. The result: enhanced UGR performance, helping to meet stringent low-glare requirements in office, industrial, and commercial spaces.
This product is not a replacement for our existing glare diffusers, but rather a performance-enhancing product. Eclipse works in synergy with BrightView's existing glare control structures, providing lighting designers with a new tool to fine-tune luminaires for optimal comfort and compliance.

G Series Glare Control and Gain Diffusers
Glare Suppression
G Series glare control 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 patented² and patent-pending diffusers, unlike conventional prismatic sheets, have a soft cutoff with no color separation, resulting in enhanced visual appeal and LED hiding capability.

Instructions for use:
- G Series anti-glare diffusers must be flat to achieve the anti-glare effect; they cannot be curved around the lamp.
- G Series glare control diffusers must be used with the microstructure facing toward the LED or lamp.
- Helps luminaires meet ANSI/IESNA RP-1-04 and EN12464 glare standards for office/indoor lighting.
- Glare suppression and efficiency are typical; they vary significantly depending on luminaire design.
- BrightView's application engineers can assist with product selection to help your design achieve peak performance.
