Lifetime of LEDs

The useful lifetime of LED luminaires is very long and can reach up to 50,000 hours. Even then, a LED does not fail like other lamps, it merely loses light output over a period of time during which there is little change in the subjectively perceived brightness. The failure rate is therefore much lower than for compact fluorescent lamps. The installation conditions contained in the mounting instructions should be observed if the installed components are to achieve their rated useful lifetime.
