CFL light bulb efficiency. Illustration showing the energy efficiency of a CFL (compact fluorescent lamp) light bulb. 60% of the electrical energy of this 30 watt light bulb is converted into light,producing 1600 lumens of illumination. 12 watts (40%) is lost as heat. The energy efficiency of CFL light bulbs is several times better than incandescent lamps,but not as great as LED (light-emitting diode) lamps | |
