How long does the EL lamp last in ASSA ABLOY Group companies’ door and hardware applications?
Unlike conventional lamps, EL will not burnout. There is no filament to break or gas to escape. EL, like LEDs, does loose some of there brightness over time. The life of the lamp is related to how bright (how much voltage and frequency) the Lamp is operated at, as well as its duty cycle and the acceptable light output for the application. We call this the USEFULL LIFE. In Emergency Egress Lighting applications, the Lamp is operated at a high brightness level but for a very short duty cycle when connected to the fire alarm system. In this application, the Lamp has an indefinite Useful Life. The lamp does not “burnout”, only that it may become dim enough to require replacement.
