Lamp life

Lamp life

Varies from source to source.

rated lamp life

% rated lamp life vs. % of initial lamps which survive A life expectancy curve for incandescent lamps
1. The average life of a lamp of a given type, as determined from a large sample operated under laboratory conditions; the average life of a group of lamps which are operated under variable conditions may not equal the rated lamp life.
2. For lamp types whose luminous output drops to a very low value before the lamps cease to operate: the time when the output of a large sample of lamps under controlled laboratory conditions reaches a specified fraction of the initial output.
