What is 3mm ultra thin LED strip?
The LED COB Ultra Narrow strip light is a high-density linear lighting solution that utilizes advanced Chip-On-Board (COB) technology, where LED chips are directly mounted onto a flexible PCB to deliver a seamless, dot-free glow. With an ultra-slim width typically ranging from 3mm to 5mm, it is significantly narrower than traditional LED strips, making it ideal for applications with extremely limited space or requiring precise, refined lighting—such as cabinet gaps, cove lighting, display cases, art installations, and commercial edges. Despite its compact size, it retains all the advantages of COB technology, including high brightness, flexibility, glare-free uniform illumination, and excellent color consistency. The ultra narrow design allows for discreet and creative installations, making it a perfect choice for modern lighting designs that prioritize minimalism and detail-oriented aesthetics.

FAQ – Ultra Narrow COB LED Strip
1. What is an ultra narrow LED strip?
An ultra narrow LED strip is a slim lighting solution with a width of 3mm to 5mm. It is designed for tight spaces where standard LED strips cannot fit.
2. What is the difference between COB and SMD LED strips?
COB LED strips provide dotless and uniform lighting with no visible light points. SMD LED strips show individual LED dots and are less suitable for narrow applications.
3. Where can ultra narrow LED strips be used?
They are widely used for cabinet lighting, display cases, furniture, and architectural lighting. Their slim design makes them ideal for hidden and decorative lighting applications.
