Lamp life
There are a confusing number of definitions for lamp
life, and these differ from one region to the next and
from one application to the next. The basic definitions
for the most common types are given below.
This document refers explicitly only to the average life.
Average number of hours burned over several groups
in which in the group in question half the lamps have
failed as the result of a defect (corresponds to 50%
failure).
Quantity of working lamps of a group of lamps after
a defined number of burning hours.
Average value of some groups.

Minimum period of time in which a lamp remains in
operation under laboratory conditions.
Period of time between group relamping of an instal-
lation under the condition that operating costs are
minimised and the installation luminous flux does not
fall below a particular value. This will vary according
to the application.
Simplified practical view of the economical life.
This is the operating time after which the installation
luminous flux (the product of the relative luminous flux
and the lamps still in operation) is still around 70%
(sometimes 80%).
