Professional LED Diffusion Gel

The Lee Filters Zircon Diffusion 1 sheet measures 24 by 24 inches and is engineered specifically for LED lighting fixtures. It provides 1 1/3 stops of light reduction with a 43 percent transmission rate to soften output while preserving brightness. The gel helps blur individual LED pixels when placed close to the source.

Heavyweight Polyester Construction

A thick polyester substrate handles the heat intensity of LED panels without degrading quickly. The material is rated NFR for flame retardant safety during extended studio sessions. Testing shows the filter retains at least 80 percent effectiveness after eight months of continuous use on LED downlights.

1 1/3 Stop Diffusion Strength

This single density determines how much the light spreads and how soft the shadows become. It is calibrated for subtle control rather than heavy diffusion. Buyers who need stronger softening or multiple density options should select a different filter grade.
