Description

12V Ultra-Slim 3mm Blue COB Dot-Free LED Strip – Seamless Accent & Mood Lighting

This ultra-slim 3mm 12V blue COB dot-free LED strip is designed for discreet accent and mood lighting where space is extremely limited but visual impact matters. Using high-density COB technology with 400 LEDs per metre, it produces a smooth, continuous blue line of light with no visible hotspots, even at close viewing distances. Ideal for furniture lighting, marine cabins, campervans, motorhomes, display shelving, signage, and automotive interiors, this strip delivers a clean, modern aesthetic while remaining fully dimmable for precise brightness control. Its minimal size allows it to disappear into tight channels and recesses, making it perfect for applications where the light effect is seen but the fitting is not.

At just 3mm wide, this 12V blue COB Dot-Free LED Strip is one of the slimmest on the market — making it the ideal choice where space is tight or where a discreet, modern line of light is desired. Despite its tiny size, it delivers smooth, continuous blue illumination using the latest COB LED technology with 400 LEDs per metre.

Fully compatible with most 12V dimmers, this strip offers adjustable brightness for everything from subtle ambient glow to striking accent light.
