COB LED Strip Lights

COB means chip on board. Many small LED die are mounted closely together and covered by a continuous light-emitting phosphor layer. This blends their output before it leaves the strip, producing a smoother line than widely spaced packaged LEDs.

COB substantially reduces visible points and pixelation, but “dot-free” is an appearance result rather than an absolute condition. Output, dimming level, channel depth, diffuser, viewing distance, surface reflectivity and installation geometry can all affect what the eye sees.

Not always for visual blending, but a channel may still improve mounting, protection, heat transfer and the finished architectural detail, while a diffuser can reduce glare and protect the strip. Evaluate the complete assembly for the application.

Not inherently. COB and SMD describe construction, not guaranteed performance. Compare published lumens per foot for brightness and lumens per watt for efficacy, along with CRI, CCT, power, thermal conditions and optical losses.

Choose fixed white when one Kelvin value is required, tunable white when occupants must adjust between warm and cool white, or single color when the project needs a continuous red, green or blue accent. The control and wiring requirements differ for each.

Yes, but only at the marked copper cut points. Current products use approximately 1.04- or 2.46-inch intervals. Confirm the exact strip before laying out finished lengths; cutting elsewhere damages the circuit.

The current products on this category page are IP20 and intended for indoor dry locations. Do not use them where moisture, condensation or washdown is expected; select a product with the appropriate environmental rating instead.

Use the product's measured power-by-length data where available, then add the capacity headroom specified for the power supply and controller. Stay within the listed maximum run, verify wire gauge and voltage drop, and use additional feeds or parallel runs where required.
