Ultra-high Reflectivity Increases Luminaire Efficiency

Bright White Reflector

BrightWhite™ diffuse, white reflectors provide ultra-high reflectivity for use in lighting, illumination, displays, and signage. Luminaires lined with BrightWhite™ reflectors can provide up to 30% more light output than those lined with white paint, solder mask, or powder coat.

BrightWhite™ reflectors are available as a film, with or without adhesive. They are easily and cleanly cut using laser, die, shear, or blade cutters. Shapes can be created with standard thermoforming techniques to line the interior surfaces of luminaires. Metal versions are compatible with shear, punch, roll, and other standard sheet metal processes.

Performance Data



Available Width Continuous rolls up to 52 inches wide, with optional adhesive and removable liner

Available form factors Roll, sheet, cut parts, thermoformed shapes

Masking Available with an easily-removable protective masking film. Many customers elect to operate without masking due to the durability and cleanability of the BrightWhite™ film

Thermal Stability Less than 0.5% reflectance change after 1000 hours exposure to 80°C
Humidity Stability Less than 0.5% reflectance change after 1000 hours exposure to 60°C and 95% RH
Cleaning Water and gentle detergent recommended. Tolerates general household cleaners containing chlorine and ammonia cleaning agents
Mechanical Easily cut, creased, thermoformed, etc. Inquire for details

Form Factors and Converting

Roll and Sheet

BrightWhite™ white reflectors are available in roll and sheet form, up to 52 inch width. Available with removable protective masking film. Also available with adhesive and easily-removable liner.

Cut Parts

BrightWhite™ reflectors are easily cut by standard methods, and leave clean edges with no fraying. Bright View can provide BrightWhite™ reflectors precisely cut to customer drawings, or can work with your preferred converter.

Thermoformed Parts

BrightWhite™ reflectors can be easily thermoformed into 3D shapes using standard processes and equipment. Thicker grades are offered specifically for thermoforming. Bright View can directly supply formed parts or provide process parameters to customers’ preferred converter/thermoformer.


BrightWhite™ reflectors are available on steel or aluminum, and are readily formable using industry-standard processes.

Usage Notes

  • BrightWhite™ reflectors can increase the output of light fixtures by up to 30% when installed properly
  • BrightWhite™ reflectors are most effective when combined with high-efficiency diffusers, such as Bright View diffusers
  • For best performance, cover all interior surfaces of the luminaire with BrightWhite™ reflector and avoid creating narrow corners or overlaps that could serve as “light traps”
  • For best performance, angle the sides of the BrightWhite™ reflector outward toward the diffuser
