5mm Round Red Diffused Led (Pack of 10) Clock & Timer IC respectively5mm Red Led (Pack of 10) A Red 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 and the colour of the
