Well, that's not strictly true, but the life of an LED is far longer than that of a standard bulb (btw, they call them lamps in the lighting industry ).
Unlike most traditional light sources, LEDs do not fail catastrophically. Instead, the light output of LEDs degrades over time. Therefore, the useful life of an LED lighting system can be defined by the time when it fails to provide sufficient light for an intended application.
System life quoted by manufacturers, commonly 100,000 hours, is often based on the lifespan of a single LED. However, the average performance of a single LED cannot be used as an indicator of an LED system, which may contain multiple LEDs, circuit boards, housing, lenses, and other components that, when combined, affect performance.
