My incandescent bulb just burned out...how do I know which type of CFL to select?
When you are ready to replace an old incandescent bulb with a CFL, it's best to know what your needs are before you make a purchase. Check out these tips from ENERGY STAR to help you make a good selection, and choose the best places to begin installing CFLs.
- 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 socket fixture, 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 your home. FOr example, while most CFLs provide warm or soft white light for your home, you could also 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.
You should also check the lumen rating to find the right CFL. The higher the lumen rating, the greater the light output. Look at the chart below to determine which CFL wattage is best to replace your incandescent bulb.
