How to Use CFL Bulbs in Enclosed Fittings
Compact fluorescent lights, or CFLs, are energy-efficient bulbs that last about 10 times longer than traditional incandescent bulbs, according to Energy Star. Using CFLs in your home can save time, energy and money, and they can be used almost anywhere. Enclosed fittings with little airflow can reduce the life expectancy of CFLs, however. In some cases, you will need special bulbs for such areas. Does this Spark an idea?

Look at your light fitting. If it is an indoor recessed can light -- one completely recessed into a ceiling or wall and covered -- you will need a CFL designed for use in such fittings. Look for a bulb labeled "indoor reflector," which can operate efficiently at the high temperatures that result from lack of airflow in completely enclosed spaces. If the fitting is enclosed but not recessed, you can use a regular CFL if you prefer.

Purchase a standard spiral-shaped CFL for use in outdoor enclosed fittings. You can also use covered A-shaped CFLs, tube CFLs or candle CFLs in enclosed outdoor fixtures, according to Energy Star.

Screw the appropriate bulb into the fitting by holding onto the ballast, which is the plastic white part at the bottom of the bulb. Do not hold the glass tubing.

Tips & Warnings
Using standard CFLs in enclosed spaces can result in shorter bulb life due to the higher temperature, according to the Michigan Department of Environmental Quality. The bulb should still last much longer than an incandescent bulb, however. Visit energystar.gov for tips on using CFLs, including detailed buying tips and a product search to help you find the correct bulb for your fitting.
CFLs contain a small amount of mercury, which can be dangerous to humans. If a CFL breaks, you need to take precautions when you clean up. Visit the U.S. Environmental Protection Agency's website (epa.gov) for specific instructions.
