LED channels are useful for LED strip light installations where the lighting will be visible, such as on the underside of a shelf or in a display cabinet, or to soften lighting to minimize reflective hot spots on nearby surfaces. These 39" LED strip light diffusers, or aluminum extrusions, are made from high quality, double-anodized, aviation-grade aluminum alloy and they can be cut to length using a fine-tooth handsaw and run in sequence to create a longer fixture. Wide Surface Mount models are ideal for multicolor and outdoor LED strip light. The included brackets guarantee easy and secure mounting to the desired surface, and can also be used as connectors between channels. Channels come in packs of 5.
