Pick the perfect LED

Upgrade to energy-efficient ENERGY STAR® LEDs and get instant discounts—up to $7 per bulb—at participating retailers. LEDs last up to 25 times longer than incandescents and use 75 percent less energy, meaning you save energy and save money. LED lights have a number of benefits, but many people feel overwhelmed when picking the right one for their home. Know what to look for when you pick your next light.


There are three main categories of color and you can determine the shade that best meets your needs by selecting the appropriate color temperature number on the packaging.




Warm white, soft white 2700 or 3000K Standard color of traditional bulbs
Cool white, natural white 3500 or 4100K Good for kitchens and work spaces
Natural or daylight (blue-white) 6000K and higher Good for reading because it increases contrast


The lumen number indicates the brightness. The higher the lumen, the brighter the bulb.




1600 lumens 100 Watt 16–20 Watt
1100 lumens 75 Watt 9–13 Watt
800 lumens 60 Watt 8–12 Watt



The best way to determine light efficiency is to look at the Lumens per Watt, which shows how much light you get for each Watt used. Old-fashioned bulbs produced 10 to 15 lumens per watt, and fluorescent tubes produce about 50 to 100 lumens per Watt. LED lights can range from 20 to 60. The more lumens per watt, the brighter the output for less energy used.
