Lamp life and

luminous flux
Typical failure distributions are shown in mortality curves.
Because of chemical changes in the phosphor, the luminous flux of a fluorescent lamp
decreases as the lamp ages. The term „maintenance“ is used to indicate how well
luminous flux is retained throughout the life of the lamp. The loss of luminous flux for
the trichrome phosphors (LUMILUX

There are several definitions of lamp life and these are applied differently depending
on the type of lamp, the lamp manufacturer and the geographical region. The most
important definitions for compact fluorescent lamps are given below.
Lamp life is the period of time during which a lamp can be operated until it is un-
usable (electrical failure, too little light).
Average rated lamp life is the average value of the life values of individual lamps
operated under standardised conditions (50 % failure). In other words, this is the
period of time in which for a standardised 3-hour switching cycle (165 minutes on/15
minutes off in accordance with IEC 60901) 50 % of the lamps fail.
