How long do LEDs last?
The short answer is 10 – 20 years for home applications where the LED bulb is normally burned for the typical 1 – 3 hours/day. The rated life of an LED bulb is based upon burning hours, and typically life ratings for LED household bulbs are 10,000 hours or more, with some rating as long as 40,000 – 50,000 hours starting in 2017. However, LED bulbs are not likely to fail by simply burning out. It is more likely that they will just gradually get dimmer over time. To claim a rated life of 15,000 hours, for example, Energy Star-qualified bulbs must pass sample tests that require they produce no less than 93.1 percent of their initial light output after they have been burning for 3,000 hours.
