Compact fluorescent lamps/lightbulbs (CFLs) use about one-fourth of the energy a standard bulb uses to produce the same amount of light. Not only can you use a bulb with a much lower wattage requirement (e.g., replacing a standard 100 watt incandescent with a 29 watt CFL), but the bulb will last six to ten times longer than an incandescent. You can expect about 10,000 hours from your CFL as opposed to about 1,000 hours from an incandescent. The energy savings (around 141 kWh of electricity annually in this case), and greatly extended life of the bulb offsets the higher initial cost of the product. Here are examples of standard incandescent bulbs and their CFL equivalents for the same amount of light. The reduction in energy use is impressive: Incandescent 40 watt = CFL 10 - 13 watt Incandescent 60 watt = CFL 14 - 19 watt Incandescent 75 watt = CFL 20 - 25 watt Incandescent 100 watt = CFL 29+ watt If you are not getting the expected life from a CFL, check the package and fine print for that bulb's use and conditions. Match the bulb selection to the fixture and conditions.  For more information go to http://Light Bulbs : ENERGY STAR  For information on early bulb burnout, go to Bulb burn out
