USB-Powered Blue COB Strip

This 3.28-foot blue LED strip uses Flip Chip On Board technology with 320 LEDs per metre to produce uniform, high-CRI light from a standard 5 V USB port. It suits hobbyists, display builders and anyone wanting simple accent lighting without a separate power supply. The 8 mm width fits tight channels under cabinets, behind monitors or inside 3D-printer enclosures. No soldering or controller is required.

Plug-In Installation Flexibility

The 25 cm USB lead connects directly to laptop ports, phone chargers, power banks, TV USB sockets or car chargers, so the strip works wherever 5 V USB power exists. Double-layer copper PCB improves conductivity and heat spread, while the pre-applied 3M tape adheres to clean indoor surfaces. IP30 rating limits use to dry locations only. No external driver or wiring harness is needed.

Ready-to-Use Accessories

Strong 3M adhesive backing is already mounted, eliminating separate tape purchases and speeding installation. The 180° beam angle spreads light evenly across surfaces for backlighting, under-cabinet tasks or mood lighting. Rated lifespan exceeds 65,000 hours of continuous operation. Blue single-colour output means no remote, controller or colour-mixing hardware to configure.
