The Energy Labeling Rule requires light bulb manufacturers to give consumers key information in an easy-to-read format.

The Lighting Facts label is modeled on the Nutrition Facts label on food packages. It gives shoppers the information they need to buy the most energy-efficient bulb to meet their lighting needs. The label includes a bulb’s brightness, energy cost, life, light appearance, and wattage. In addition, the principal display panel on the front of packaging focuses on lumens, a measure of brightness, rather than on watts, a measure of the amount of energy used, and includes the estimated yearly energy cost for each bulb. Bulbs themselves also feature lumens, and in the case of CFLs, a mercury disclosure.

The Lighting Facts label must be on the side or rear panel of the package, and must include:

  • the light output of each lamp included in the package, expressed as “Brightness” in average initial lumens rounded to the nearest five
  • the estimated annual energy cost of each lamp included in the package based on the average initial wattage, a usage rate of 3 hours per day, and 11 cents ($0.11) per kWh
  • the life of each lamp included in the package, expressed in years rounded to the nearest tenth (based on 3 hours operation per day)
  • the correlated color temperature of each lamp included in the package, as measured in degrees Kelvin, and expressed as “Light Appearance,” and by a number and a marker placed proportionately on a scale ranging from 2,600 K on the left to 6,600 K on the right
  • the wattage for each lamp included in the package, expressed as “Energy Used” in average initial wattage
  • the ENERGY STAR logo for qualified products, if you wish. Only manufacturers who have signed a Memorandum of Understanding with the Department of Energy or the Environmental Protection Agency may add the ENERGY STAR logo to labels on qualifying covered products, and they may add the ENERGY STAR logo to labels only on those products covered by the Memorandum of Understanding
  • the design voltage of each lamp included in the package, if other than 120 volts
  • for any general service lamp containing mercury, the following statement: “Contains Mercury / For more on clean up and safe disposal, visit epa.gov/cfl.” You also may print an “Hg[Encircled]” symbol on the label after the term “Contains Mercury.”
