Opencircuit Warm white 10W LED Chips - 2 pcs

A set of 2 LED chips with a power of 10W and a warm white light color (3000K-3500K). These LED chips contain 9 small 1W LEDs which are integrated together in 1 chip, so that these LEDs emit an enormous amount of light (900 lumens). These LEDs must be connected to a 10W LED driver which can supply 9V to 12V with a power of 850mA. It is also necessary to place these LEDs with thermal paste on a heatsink for heat dissipation.
