Compact Fluorescent Lamp Energy saving lamp Operating Voltage: 110-130V or 220-240V Frequency: 50/60Hz Average lifetime: 6,000hours, 8,000hours, 10,000hours Optional base: E27,E14 or B22 Color Temperature: 2,700 and 6,400K Energy saving lamp: Benefits. Efficient: CFLs are four times more efficient and last up to 10 times longer than incandescent.A 22 watt CFL have about the same light output as a 100 watt incandescent. CFLs use 50-80% less energy than incandescents.Less expensive: Although initially more expensive, you save money in the long run because CFLs use 1/3 the electricity and last up to 10 times as long as incandescents. A single 18 watt CFL used in place of a 75 watt incandescent will save about 570 kwh over its lifetime.At 8 cents per kwh, that equated to a $45 savings.Environmental Protection: reduce Air and Water pollution. Replacing a single incandescent bulb with a CFL will keep a half – ton of CO2 out of the atmosphere over the life of the bulb.H-quality light: Newer CFLs give a warm, inviting light instead of the “cool white” light of the older fluorescents.
