An apparatus, system, and method for increasing life of a high intensity
lighting fixture light source. In one aspect, the method involves
installing a new HID lamp in the fixture in combination with retrofitting
a circuit that operates the lamp at a reduced wattage over a substantial
period of operation time to save energy. In another aspect, the circuit
comprises switchable capacitants adopted to operate the lamp at a reduced
wattage over a substantial period of operation time. In another aspect of
the invention, instead of retrofitting, the entire lighting fixture could
be replaced at the end of a predetermined operating period and replaced
with a balasting system that includes switchable levels of capacitants to
reduce operating wattage to the lamp for at least the first substantial
operating period.
