3W Cold White LED on Star Board Heatsink
High intensity cold white LED module. 3W LED is mounted to star style aluminum heat sink with heat sink compound between the LED and the heat sink. These are the same LEDs found in many high intensity LED flashlights and lanterns. Solder your connection wires to the silver rectangles marked with "+" signs for positive and "-" signs for negative. NOTE: The star heat sink on this LED cannot fully dissipate a full 3W of heat. Therefore, to drive this LED at its highest power for extended periods of time you will need to add additional heat sinking. We recommend our 3W LED Heatsink.
