LED is best; here’s why


A light-emitting diode (LED) bulb is an energy-efficient light bulb that generates light from the movement of electrons through a semiconductor.

LED bulbs use at least 80 percent less energy than traditional incandescent bulbs and can last 13-25 years longer. LED bulbs are more energy-efficient than any other type of light bulb on the market (see our comparison infographic below). LEDs are environmentally friendly, too, which means you can safely dispose of them in the trash.

And did you also know:

  • LED bulbs use at least 80 percent less energy while producing the same quality and brightness of light that customers are used to getting from old incandescent and CFL bulbs.
  • LED bulbs have dimmable options that help you use even less energy. Be sure to use dimmable bulbs in dimmable fixtures.
  • You can use an energy-efficient LED bulb as a stronger light source without exceeding a fixture's maximum-rated wattage — great for boosting brightness in less well-lit areas.
  • LED bulbs last 13-25 years longer than incandescent bulbs. Their extended lifetime means fewer stores to visit and bulbs to buy in the long run.
  • Today's ENERGY STAR® qualified bulbs turn on immediately and do not flicker or buzz.
