Used with the aluminum channels offered separately, these polymer covers conceal the LEDs and diffuse the light output. They are particularly useful where installed lighting will be visible, such as on the underside of a shelf or in a display cabinet, or to soften lighting to eliminate reflective hotspots on a nearby surface. The diffusers can be cut to length using a fine-tooth handsaw.
Choose the diffuser according to the type of channel you will install: surface-mount, flush-mount or corner-mount. The diffusers are available with frosted (translucent) or opal (milky) surface finishes. The frosted diffuser allows good light transmission, but the LED lights are somewhat visible. The opal diffuser provides more uniform light diffusion and good LED concealment.
Note that each diffuser is specific to the channel type; for example, diffusers for flush-mount channels cannot be fitted to surface-mount channels.
