Common CFL Myths

United States retailers will soon begin switching out traditional incandescent lightbulbs with more efficient options because of new regulations under the federal Energy Independence and Security Act of 2007. Compact fluorescent lamps (CFLs) are the most widely available technology that meets the law’s provisions. As consumers rely more heavily on CFLs, they will encounter misconceptions—myths that the Electric Power Research Institute (EPRI), a non-profit research consortium made up of electric utilities, including electric cooperatives, wants to dispel.

Myth #1. CFLs cannot be used in 3-way fixtures.

Several manufacturers have developed 3-way CFLs that provide performance equivalent to traditional 3-way incandescent lamps and also operate in standard 3-way sockets.

Myth #2. Dimmable CFLs do not work with standard line dimmers.

While dimmable CFLs are available today, not all dimmable CFLs are compatible with every dimmer. Read the package before purchasing to determine if the CFL dims.

Myth #3. CFLs do not last as long as advertised.

Installing CFLs in recessed can fixtures not rated for its use will likely shorten the lamp’s life. The life of a CFL also depends on how frequently the consumer turns it on and off.

Myth #4. CFLs do not fit in fans or candelabras.

Lamp manufacturers have developed CFL products of various wattages and designs that can be screwed directly into specialized fixtures such as fans, candelabras, chandeliers, and wall sconces. 

Myth #5. CFLs are too expensive, and energy savings are outweighed by disposal costs.

The cost of CFLs has dropped significantly, and it’s easy to recycle used or damaged bulbs. To learn more, visit www.epa.gov/cflcleanup.
