How Long Do LEDs Last?


One of the major advantages of LEDs is their potentially long life. LEDs don't usually burn out, instead they gradually fade over time. This process is called lumen depreciation. Factors that contribute to lumen depreciation include drive current and the heat generated within the device itself. Good quality white LEDs in well-designed fixtures are expected to have a useful life of 30,000 to 50,000 hours, depending on operating conditions and other factors. At 24 hours of continuous use, such fixtures can deliver useful light for six years or longer – much longer than incandescent sources and up to twice as long as long-life fluorescent sources.
