Efficient Lighting

Switching out old light bulbs for ENERGY STAR® certified LEDs is one of the easiest ways you can start saving energy at home. Compared to incandescent lighting, ENERGY STAR certified LEDs:

  • Use up to 90 percent less energy.
  • Last up to 15 times longer.
  • Save up to $80 in electricity costs over each bulb's lifetime.
  • LEDs that have earned the ENERGY STAR label offer high quality and performance, and usually last longer than traditional bulbs.

Find the Right Bulb for Your Room

Energy-saving LEDs come in so many different styles, it can sometimes be hard to choose. But don’t fret, finding your perfect match is easy when you know what to look for.

Look for Lumens

Unlike traditional bulbs, measured in watts, LEDs are all about the lumens. The higher you go, the brighter the bulb.
