A light-emitting diode (LED) uses a semiconductor diode to generate energy in the form of a photon (light). Low power LEDs are fractional wattage devices, typically 0.1 watt. They operate at low current and low voltage, and produce 2 to 4 lumens. High power LEDs are driven at much higher current and can produce 40-80 lumens per 1-watt package.
