Earning the ENERGY STAR means products meet strict energy efficiency guidelines set by the US Environmental Protection Agency. Lighting products that have earned the ENERGY STAR deliver exceptional features, while using less energy. Saving energy helps you save money on utility bills and protect the environment by reducing greenhouse gas emissions in the fight against climate change.

An ENERGY STAR certified light bulb:

  • Saves money about $6 a year in electricity costs and can save $40 to $135 over its lifetime
  • Meets strict performance requirements that are tested and certified by a third party
  • Uses about 75% less energy than a traditional incandescent bulb and lasts 10 to 25 times longer
  • Produces about 75% less heat, so it’s safer to operate and can cut energy costs associated with home cooling

Did You Know?

If every American home replaced just one light bulb with a light bulb that's earned the ENERGY STAR, we would save enough energy to light 3 million homes for a year, save about $680 million in annual energy costs, and prevent 9 billion pounds of greenhouse gas emissions per year, equivalent to those from about 800,000 cars.
