Elliptical LED Diffusers

E-Series Asymmetric Diffusers

E-Series elliptical diffusers spread asymmetrically – more strongly in one direction than the other. They are used to diffuse a line of LEDs into a smooth line or to blend adjacent fluorescent lamps. They are also used to provide optimum spreading in wall-wash, linear, and cove applications. Because diffusion is only applied along one direction, efficiency can be even higher than C-Series diffusers. BrightView’s unique design causes less scalloping than other approaches, giving a smoother visual result.

Usage Notes:

For lamp hiding as pictured above, E-Series diffusers are directional and are generally used with the microstructures facing away from the LEDs or lamps; please try both orientations. For light spreading in wall-wash and cove applications, E-Series diffusers are generally used with the microstructures facing toward the LEDs or lamps; please try both orientations. BrightView applications engineers can assist with product choices and help your design achieve peak performance
