UGR Glare Reduction

Disabling glare from luminaires is an increasing concern in today’s environments. WhiteOptics® diffusion films for glare reduction (DFGR series) provide ultimate control by using precise microstructure optics to redirect high angle light into useful zones. This reduction in glare results in much more visually comfortable lighting and a significantly lower Unified Glare Rating (UGR).

Why Glare Reduction Is Critical

Lighting designers expect luminaire solutions will aid in creating sustained productivity while emphasizing comfort and health. Glare emitted from lighting is one of the major concerns that can reduce productivity. Combatting glare from luminaires is one of the key measures to improve the visual comfort of lighting in spaces and create a more productive environment.

The lighting industry uses Unified Glare Ratings (UGR) to convey the best application for luminaires, so that lighting designers and specifiers can deliver healthier environments that meet WELL Building Institute guidelines and the IES recommendationsfor creating comfortable spaces. Reduced UGR is now also a requirement for DLC Premium qualification and many utility rebate programs.WhiteOptics® F16 high reflectance white film improves fixture efficiency while diffusing the light and minimizing LED ‘hotspots.” You can place our film in cavities and over LED PCBs to maximize every available Lumen per watt. Our WhiteOptics F16 film offers 98 percent reflectance and is available with or without pressure sensitive adhesive backing. Available in pre-cut sheets and rolls up to 50″ wide with flexible minimum order quantities.
