LED Channel
An aluminum housing that mounts LED strips for a professional finish. Includes a diffuser cover that eliminates visible LED dots and improves heat dissipation.
The difference between an amateur LED strip installation and a professional one is almost always the channel. A bare strip stuck to the underside of a cabinet with adhesive backing looks cheap — you see individual LED dots, the light is uneven, and the strip eventually peels off. The same strip inside an aluminum channel with a frosted diffuser produces a smooth, continuous line of light that looks intentional and permanent.
Aluminum channels serve three functions: diffusion (the frosted or opal cover blends individual LED dots into even light), heat dissipation (the aluminum body acts as a heat sink, significantly extending strip life), and mounting (the channel screws or clips securely to surfaces with no risk of peeling).
Channels come in several profiles. Surface mount (flat, sticks on or screws to a surface) is the most common. Recessed channels sit flush with the mounting surface for a seamless look. Corner channels mount at 45° angles for cove or cabinet edge lighting. Pendant channels hang from cables for linear suspended fixtures. Width matters too — make sure your strip's width fits the channel's internal dimensions.

Related Terms
- COB (Chip on Board)
A dense array of LED chips bonded directly to a substrate, producing a seamless, dot-free light output. Used in high-end strip lights and downlights.
- LED Density
The number of LED chips per meter on a strip light. Higher density produces smoother, more even light with fewer visible dots. Common values: 30, 60, 120, or 144 LEDs/m.
- Heat Sink
A component (usually aluminum) that absorbs and dissipates heat from LED chips. Critical for lifespan — LEDs don't burn out, they overheat.
