The 400 LEELux Filter from LEE Filters can be applied over a lighting fixture for a dense, white diffusion effect with a wide beam spread. This filter also reduces contrast between highlight areas in a scene and creates an even, soft field of light without shadows.
Under 6774K Source C light, the 400 LEELux Filter provides a 1.5-stop value, transmitting light at 36%. It is constructed from a 125-micron polyester base that is heat resistant to 356°F and is delivered as a 60" x 20' roll on a 1" core.
