LED light bulb efficiency

Videonummer 11942570
LED light bulb efficiency. Animation showing the energy efficiency of an LED (light-emitting diode) light bulb. 85% of the electrical energy of this 20 watt light bulb is converted into light, producing 1600 lumens of illumination. 3 watts are lost as heat. The energy efficiency of LED lamps is many times better than that of incandescent lamps, and significantly better than most fluorescent lamps. The lifespan of these lamps is also much longer. See K004/8880 and K004/8879 for comparison.
