Description
2B50C 4B50C Warm White COB LED Dot Matrix PCB
The 2B50C / 4B50C Warm White COB LED Dot Matrix PCB is a compact and efficient LED lighting module designed to deliver bright, smooth, and uniform illumination. It uses COB (Chip-on-Board) LED technology to provide a dense LED arrangement in a compact form factor. The warm white light output makes this LED PCB suitable for a wide range of residential, commercial, decorative, and custom lighting applications where a comfortable and uniform illumination effect is required. The compact dot-matrix arrangement allows the PCB to be integrated into custom lighting assemblies, LED fixtures, strip-light projects, and other DIY lighting solutions. The available 2B50C and 4B50C variants can be selected according to the required application and compatible electrical configuration.
