Q: What is cob light?
A: COB light (Chip on Board) is an LED technology where multiple LED chips are packed closely together on a single board. This design creates a bright, uniform light with excellent heat management, making it energy-efficient and long-lasting. It’s commonly used in various lighting applications for its high lumen output and even illumination.
