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