Description

The 3V–3.7V Round COB Cool White LED Light is a compact, high-efficiency Chip-On-Board (COB) LED designed to deliver strong and uniform illumination. Operating directly from 3V to 3.7V, it is ideal for Li-ion battery powered devices, flashlights, and portable lighting applications.

COB technology packs multiple LED chips into a single module, resulting in higher brightness, better heat distribution, and uniform light output. This LED is widely used in DIY lights, emergency lamps, torches, Arduino projects, and battery-powered electronics.
