Why should I choose ENERGY STAR® certified LED lighting products?

There are more lighting options available today than ever before. Despite that, ENERGY STAR® is still the simple choice to save on your utility bills.

Light DistributionLED bulbs that have earned the ENERGY STAR® are subject to very specific requirements designed to replicate the experience you are used to with a standard bulb—so they can be used for a wide variety of applications. As the graphic on the right demonstrates, a general purpose LED bulb that does not qualify for the ENERGY STAR® may not distribute light everywhere and could prove to be a disappointment if used in a table lamp.

ENERGY STAR® means high quality and performance, particularly in the following areas:

Color Quality

  • 5 different requirements for color to ensure quality up front and over time

Light Output

  • Light output minimums to ensure you get enough light
  • Light distribution requirements to ensure the light goes where you need it
  • Guidelines for equivalency claims to take the guess-work out of replacement

Peace of mind

  • Verified compliance with more than 20 requirements to address performance and labeling
  • Long-term testing to back up lifetime claims
  • Testing to stress the products in operating environments similar to how you will use the product in your home
  • 3-year minimum warranty requirement
  • And as with all ENERGY STAR® products, certified LED bulbs are subject to random testing every year to ensure they continue to meet the ENERGY STAR® requirements.
