3mm White Green LED (Pack of 10) Batteries & Power Supply This configuration gives a much3mm White Green LED (Pack of 10) The 3mm White green light emitting diode (LED) is a semiconductor light source. LED's are used as indicator lamps in many devices and are increasingly used for other lighting. It looks like a white led and illuminate's blue light. When a light emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence
