Replace your inefficient light bulbs with LEDs

Why? Light-emitting diode (LED) light bulbs save electricity by using up to 90% less energy to produce the same amount of light as conventional incandescent bulbs. Though they may cost more to buy, LED bulbs last 25 times longer and cost much less to keep on, saving a lot of money in the long run.
What to look for:
  • Choose ENERGY STAR® certified LED bulbs for guaranteed efficiency and performance. ENERGY STAR bulbs maintain consistent quality over their lifetime and have a three-year warranty.
  • Task lighting. LEDs focus light in a specific direction, making them ideal for task lighting in your home. Consider using LED bulbs with task lighting fixtures such as recessed kitchen lights, desk lamps, and outdoor path lighting.
  • Variety of options. Today's LEDs come in a variety of colors and shapes to suit most lighting fixtures, so you can choose the bulb that meets your needs and preferences. Look for bulbs with a correlated color temperature (CCT) of around 2700°K to produce the same warm white light color quality as your favorite incandescent bulbs.

Things to think about:

  • LEDs light up instantly, don't flicker, and usually accommodate convenient features like dimmers and motion sensors that make saving energy easy.
  • LEDs direct heat away from the bulb, which significantly extends its lifetime by preventing overheating. This also reduces the amount of heat emitted in your home, so switching may even help you save on cooling costs!
  • LEDs are becoming more popular and affordable every year, and prices will continue to drop as demand increases.
  • Install efficient LEDs where you use light most often, such as in the kitchen, family room, or outside. For maximum savings, replace all your light bulbs with LEDs.
