COB LED (Chip-On-Board) is a new technology with many advantages, such as high brightness, better luminous efficiency, high heat dissipation efficiency, lower light attenuation, longer lifetime. Besides the light sources can be assembled as per customers’ need, and each light source is independent & replaceable, when one fails, it won't affect the lighting functions of others.
