USB-powered COB strip for compact spaces

This 3.28-foot COB LED strip draws power from any USB port, making it a plug-and-play choice for renters, students or anyone who wants accent lighting without wiring. The built-in three-button controller adjusts brightness instantly, and the adhesive backing mounts on clean, smooth surfaces in seconds.

Fits tight gaps and frees up outlets

At 39.36 inches long the strip tucks under cabinets, behind monitors or along shelf edges where longer reels would not fit. USB power means you can run it from a TV port, laptop or power bank, leaving wall sockets free for other devices. The 5 V supply keeps heat low and the light safe to touch.

Replaces hardwired puck lights

It removes the need for a transformer, switch wiring or a separate dimmer module. The jump is worth it when you want dot-free RGB colour mixing in a single-metre run that you can move or remove without tools or permanent marks.

Questions about this item

What is the maximum voltage this strip can handle before it overheats?

The strip runs on a 12 V supply but is powered through a 5 V USB connection, so the 5 V limit is what protects it from excess heat.

How much heat does the 5 V USB power supply add to a cabinet after hours of use?

The 5 V low-voltage design keeps heat output low, and the plastic housing stays cool to the touch even during extended runs.

Does the built-in controller need a separate power adapter or does it draw from the USB port?

The 3-button controller is powered directly from the same USB port that feeds the strip, so no extra adapter is required.
