Typical incandescent bulbs last 1,000 to 2,000 hours. But in speaking about LED replacements, lamp life is routinely quoted as 25,000 to 50,000 hours. Long lamp life, and the reduced power used to create the same amount of light, is what makes this technology so promising.ne thing we do know: It means something different than when people think about the life of a regular light bulb. When itâs said that a standard light bulb will last 1,000 hours, that is the mean time to failure: half the bulbs will fail by that point.
