The filament parameters are chosen for a specific operating voltage. Lamp life
is the average life of a number of lamps run in open air at the “rated voltage.”
Operating these lamps at a higher voltage greatly reduces the life. A 6%
increase in voltage reduces the operating life by 50% (Fig. 6). A small
reduction in voltage gives a longer lamp life; a reduction of more than 10% may
drastically shorten lamp life as the halogen cycle cannot operate effectively
under this condition.
