Choose the right light

Matching the right CFL (compact fluorescent light) bulb to the right kind of fixture helps ensure that it will perform properly and last a long time.

For example, CFLs perform best in open fixtures that allow airflow, such as table and floor lamps, wall sconces, pendants and outdoor fixtures. For recessed fixtures, it is better to use a reflector CFL than a spiral CFL since the design of the reflector evenly distributes the light down to your task area.

If a light fixture is connected to a dimmer or three-way switch, you'll need to use a special Energy Star-qualified CFL designed to work in these applications. Make sure to look for CFLs that specify use with dimmers or three-way fixtures.

Choose a qualified CFL that offers a shade of white light that works best for you. For example, while most CFLs provide warm or soft white light for your home, you could choose a cooler color for task lighting.

To choose the Energy Star-qualified CFL with the right amount of light, find a qualified CFL that is labeled as equivalent to the incandescent bulb you are replacing. Light bulb manufacturers include this information right on the product packaging to make it easy for consumers to choose the equivalent bulb. Common terms include "Soft White 60" or "60 Watt Replacement."
