Compact Fluorescent Lights

Compact Fluorescent Light Bulbs

About CFLs:

Compact Fluorescent Lights (CFLs) use a different, more advanced technology than incandescent light bulbs and come in a range of styles and sizes based on brand and purpose. CFLs have been manufactured for over 20 years, and have come a long way! They now provide warm, inviting and lasting light without the flicker and hum of older fluorescent lamps

Save Money with CFLs:

CFL prices range from $5 to $15, but save you approximately $25 per bulb in energy savings over their lifetime, more than offsetting the initial cost. We recommend replacing your five most frequently used lights, whether indoor or outdoor. The more bulbs you replace, the more you'll save.

With CFLs you enjoy the same amount of light as standard bulbs, but use less energy. By using less energy, you reduce pollution. In addition, CFLs last 6 to 10 times as long, saving you time buying and replacing bulbs as well as energy and money.

CFLs use less power to create the same amount of light -  use the table below to determine the correct wattage for your needs.

Regular Light Bulb Wattage CFL Replacement Wattage Electricity Savings
(over 6,000 hours, at 8 cents per kWh)
40 watts 15 watts $12
60 watts 20 watts $19
75 watts 25 watts $24
100 watts 32 watts $33

Replacing your Bulbs with CFLs:

CFLs come in a wide variety of shapes and sizes, so they can replace regular, incandescent bulbs in almost any fixture. NOTE: If you are replacing incandescent bulbs in your bathroom in an open versus enclosed fixture, make sure that the CFLs that you are choosing are rated for wet locations (check the packaging).


The best new bulbs to buy are ENERGY STAR rated CFLs. These will give you the most energy and monetary savings. Just look for the ENERGY STAR rating on the packaging!
