SpletHowever, if it is known that a percentage of the lamps are burnouts at any given time, then a light loss factor must be reckoned with. For example, if 5% of the lamps are burnouts at any given time, then this light loss factor would be 0.95. Remember that 100% rated life is defined when 50% of the lamps in a large sample of lamps have failed.
