Ultra Narrow Series LED Strip Light Index
What is Ultra Narrow COB LED strip lights?
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.

The difference between COB and SMD
Comparing to Surface Mounted Devices(SMD) led strip, COB LED strips offer wider beam angle, higher CRI and more uniform lighting. It is with a 180-degree beam angle, Free cutting of LED cob light strip. 90 CRI and dotless light illumination, flexible, energy efficiency, excellent heat dissipation and long lifespan.


Application scenarios
Worked as the thin led strip, our ultra thin COB led strips excels in illuminating confined spaces with a remarkably slim profile down to 2.7 mm width. It is particularly suited for decorative lighting applications in cabinets, bathroom installations, and similar compact environments.

How to set up the Ultra narrow COB LED Strip
The working voltage of Thin COB led strip is DC12/24V or DC5V, it needs the constant voltage led driver (LED power supply) to light up as below.

How to connect the Ultra narrow cob led light strips
We have different type of connector to fit for different led strips. There are 2pin 3pin 4pin 5pin and 6pin to fit for 5mm 6mm 8mm 10mm 12mm PCB width led strips. And there are Strip to Wire, Strip to Strip, Corner 3 different applications like below.
1. Strip to wire
When you cut lengths of the led strip from a reel and it without wire, you can select the led strip to wire connector as below.

2. Strip to strip
When you need to connecting another led strip to the existing one, you can use the led strip to strip connector as below.

3. Corner
When you need to connect led strips in Corner, you can use led strip corner connector as below.
