Energy saving lamp: Benefits

1, Efficient: CFLs are four times more efficient and last up to 10 timeslonger than incandescents. A 22 watt CFL has about the same light out put as a 100 watt incandescent. CFLs use 50-80% less energy than incandescents.

2. Less Expensive: Although initially more expensive, you save 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 kw*h over its lifetime. At 8 cents per kw*h, that equates to a $45 savings.

3. Environmental Protection: Reduces 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.

4. H-quality Light: Newer CFLs give a warm, inviting light instead of the "cool white"light of older fluorescents. They use rare earth phophors for excellent color and warmth. New electronically ballasted CFLs don't flicker or hum.

5. Versatile: CFLs can be applied nearly anywhere that incandescent lights are used. Energy-efficient CFLs can be used in recessed fixtures, table lamps, track lighting, ceiling fixtures and porchlights. 3-way CFLs are also now available for lamps with 3-way settings. Dimmable CFLs are also available for lights using a dimmer switch.

How to choose CFL
CFLs come in many shapes and sizes. When purchasing CFLs, consult the seller for commendations and consider the following:

1. Choose your preferred light quality
CFLs bulbs have a Kelvin or 'K' number on the packing. CFLs with K numbers between 2700-3000 give off a soft light like incandescents. CFLs with K numbers between 3500-6000 give off a bright light. As you go up the K number scale the light gets bluish and close to daylight.
For example:
Approx. 2700K=Warm White(looks just like incandescent)
Approx. 6400K=Cool white(white/blue, bright light)

2. Choose the shape.
CFLs are available in variety of shapes to fit a range of lamps and lighting fixtures.
CFL Models: Spiral lamps, 2U, 3U, 4U, 6U, 8U shapes lamps, standard lamps, globe lamps, flood lamps, delabra.

3. Match lumens to the incandescent being replaced.
Lumens indicate the amount of light being generated.
