The average U.S. household has about 70 light bulbs. One LED (light-emitting diode) light bulb uses up to 850% less energy than old incandescent bulbs and and has the potential to last tens of thousands of hours, so you’ll be buying and changing bulbs less frequently. 

The Lighting Facts label helps you buy the light bulbs that are right for you.

The brightness of the bulb is listed first on the label. While you may be used to thinking about brightness in terms of watts, it makes more sense to think in terms of lumens, or the amount of brightness a bulb provides—the higher the number, the brighter the bulb.

Then look at the light appearance or color of the bulb. The scale on the label will tell you whether the bulb is warm or cool.

The numbers shown are on a Kelvin (K) temperature scale.

  • For soft, white, warmer light, look for bulbs marked 2700–3000 K.
  • For a whiter light, look for bulbs marked 3500–4100 K.
  • For bluer white light or daylight, look for bulbs marked 5000–6500 K.
