Volumetric Diffusers

V-Series Volumetric Overlay


V-HE Series diffusers provide even illumination and good lamp hiding with excellent efficiency. V-Series diffusers can be used in fluorescent and LED applications when greater hiding and wider light distributions are desired relative to that of the Bright View C-Series diffusers.  They are specifically designed to meet the requirements of fluorescent general lighting, including resistance to yellowing, cracking, or embrittlement under ultraviolet (UV) exposure. They are available in continuous, seamless rolls up to 56-inch (1442 mm) width.

  • Continuous (seamless) rolls up to 56-inch (1422 mm) width
  • Cut parts in any size and volume


Usage Notes

  • V-Series diffusers are symmetric; either side can face toward the light source
  • Care should be taken not to kink the diffuser as surface blemishes can appear
  • Bright View applications engineers can assist with product choices and help your design achieve peak performance
