Average rated lamp life (B50) is the average value of the life time for an entity of lamps operated under standardized
conditions until 50% failure. In other words, this is the operation time at which, for a standardized 3- hour switching cycle (165
minutes on / 15 minutes off (according to IEC)), 50% of a sample population of lamps have failed.
13
Service life time is the mathematical life time (maintenance multiplied with the % of failed lamps e.g. B10) for lamps in
an installation after which the installation luminous flux (100 h value) decreased by 30% (decrease in luminous flux and
failed lamps) for indoor lighting
14
Lamp Lumen Maintenance Factor (Lamp luminous flux in %): Ratio of the luminous flux of a specific quantity of lamps at
a defined number of hours of operation to their luminous flux at 100 h
15
Lamp Survival Factor (Lamp Survival in %): Ratio of the number of electrically intact lamps to the total number of lamps
