Learn more about energy efficient LED bulbs

LED (light-emitting diode) bulbs are the most energy efficient type of light bulb available today. They use up to 80 percent less energy than a comparable incandescent bulb, and they can last for up to 25 years. A comparable CFL bulb will last 7 to 11 years.

  • LEDs are safer because they operate at lower temperatures
  • LEDs contain no mercury
  • They do not produce any ultraviolet (UV) light
  • They light upinstantly, with no warm-up time
  • They emit a higher percentage of bulb light in a focused direction

LED bulbs keep improving in efficiency and quality: A Nov. 4, 2014, report by the U.S. Enrgy Information reports:

Improvements in lighting technology for light-emitting diode (LED) bulbs have increased lighting efficiency, or efficacy, as well as color quality.

In September 2014, several manufacturers released ENERGY STAR®-qualified bulbs surpassing 100 lumens per watt. For comparison, traditional incandescent bulbs, which do not meet current light bulb efficiency standards and are no longer sold, provide 13 to 18 lumens per watt.

A bulb for every socket: You can purchase energy efficient LED bulbs for a variety of fixtures and uses, including dimmable bulbs, three-way bulbs, bulbs in traditional A-line, globe and candle shapes, bulbs for recessed can fixtures, and bulbs for outdoor use.

Bulb brightness: LED bulbs come in a range of light "colors" measured on the Kelvin temperature scale. Look for the "K" number on bulb packaging or the color description to get the color of light you want.

  • Warm white or soft white, standard color of incandescent bulbs, 2700K - 3000K
  • Cool white or bright white, good for kitchens and work spaces, 3500K - 4100K
  • Natural light or daylight, good for reading, 5000K - 6500K

Recessed lighting: Look for ENERGY STAR-qualified LED reflector bulbs, which are designed and tested to operate efficiently in the hot environment of a recessed can. Qualified LED reflectors provide excellent light instantly in one direction and last about 22 years. CFL reflectors are also a good choice, but have a less distinct beam of light and take a little while to reach full brightness.

Dimmers: Bulb manufacturers recommend replacing the dimmer switch when you install dimmable LED bulbs. A new switch will sense the lower range of electricity needed to power a dimmable LED bulb.

Controls: Is the fixture connected to any controls such as a timer, a motion sensor or a photo sensor? ENERGY STAR recommends that you check your controls and the bulb package to make sure they are compatible.
