COB (Chips on Board) is a new technology of LED packaging of LED light engine. Multi LED chips are packaged together as one light module. When it lights up, it looks like a lighting panel. This LED light works at DC3-4V, max 3W and gives 300LM brightness. It has a very wide use, for example car lights, table lights, wall lamp, house lighting and other LED bulbs. But like all other LED lights, this COB light will produce very much heat, so it's better to add a heatsink/ radiator when use it.
