3.28 ft COB LED strip for indoor use

The 3Key 3KEYCOB100 is a 3.28 ft COB LED strip that runs on 5 V USB power. It produces a 6000 kelvin white light at 10 W and measures 39.37 inches in length. The strip is designed for indoor locations such as bedrooms, kitchens and cabinets.

Plastic housing with adhesive backing

The light uses a plastic body with a copper finish and weighs 0.13 pounds. A self-adhesive backing allows tool-free mounting on clean, dry and smooth surfaces. USB power means it can connect to power banks, laptops or USB adapters without hardwiring.

Check USB power and surface suitability

Verify that a USB port or adapter supplying 5 V is available at the intended location. The adhesive requires a smooth, dry surface for a secure hold. The product is rated for indoor use only and carries no warranty.

Questions about this item

What does the 5 V USB power cap at in practice?

The strip draws 10 W from any 5 V USB source such as a power bank, laptop port or USB adapter and runs without hardwiring.

What clearance does the 3.28 ft strip need to fit?

The flexible plastic body measures 39.37 in long and weighs 0.13 lb, so it fits in standard cabinet, shelf or TV-backlight gaps with only a few millimetres of depth.

How is the strip installed and what step do people skip?

Peel the self-adhesive backing and press onto a clean, dry, smooth surface; the step often missed is wiping the mounting area first so the adhesive bonds securely.
