Lighting Made Easy: Brighten our planet's future with ENERGY STAR®

Even with all the new lighting choices, saving money on your electricity bill is still simple: Look for the ENERGY STAR for energy savings. No matter the technology or the performance claims, only bulbs with the ENERGY STAR label meet strict guidelines for efficiency and performance that set them apart.

Look for the ENERGY STAR: Energy star means high quality and performance. Bulbs with the label have been independently certified and undergone extensive testing.

ENERGY STAR certified bulbs use less energy, so they cost less to operate than standard incandescent bulbs. And less energy means fewer greenhouse gas emissions.

  • Use 70-90% less energy than incandescent bulbs
  • Save $30-$75 in energy bills
  • Provide the same brightness (lumens) with less energy (watts)
  • Last 10-25 times longer than incandescent bulbs
  • Help protect the environment and prevent climate change

Choosing the Right Brightness & Color: Instead of watts, look for lumens to measure the brightness of the bulb. More Lumens = More Light

Look for the light output you need to match the brightness of your old incandescent bulbs. Watts measure the amount of electricity a bulb needs to operate. ENERGY STAR certified bulbs provide the same brightness (lumens) with less energy (watts).  

ENERGY STAR bulbs are available in a wide range of colors. Light color, or appearance, matches a temperature on the Kelvin scale (K). Lower K means warmer, yellowish light, while higher K means cooler, bluer light.

ENERGY STAR certified bulbs last 10-25 times longer than standard incandescent bulbs.

  • One 9-watt LED ENERGY STAR certified light bulb. Total cost: $30
  • Two and a half 13-watt ENERGY STAR certified light bulbs. Total cost: $35
  • 25 60-watt incandescent light bulbs. Total cost: $100
  • 1 ENERGY STAR certified light bulb prevents 460-1,300 lbs. of greenhouse gas emissions over its lifetime.

Impact of ENERGY STAR: Lighting an average home can use more energy than your laundry equipment, refrigerator, and dishwasher combined.

  • The average household has approximately 30 light fixtures.
  • Nearly 70% of light bulb sockets in the U.S. still contain inefficient bulbs.

If every household replaced just one light bulb with one that has earned the ENERGY STAR we would save enough energy to light 2 million homes for a whole year and prevent greenhouse gas emissions equivalent to that of 550,000 vehicles
