Protect your LEDs and create the perfect ambiance by using an led diffuser or lens on your LED channel. LED diffusers help to evenly distribute light and eliminate hot spots, which is optimal when installing lights above reflective surfaces such as granite or glass shelving. Lenses protect the LEDs from dust and damaging agents and control the beam pattern. It's probably best to choose a channel system, which includes a diffuser or lens.
Most people don't buy just a diffuser or lens without a base unless they need to replace a broken or lost one.
