Abstract: A method for thermal control of a lamp assembly which includes an arc lamp, fan and an associated reflector enclosed within a sealed module. The method includes providing a predetermined air flow path within said module whereby a continuous flow of ambient air is passed over said lamp during lamp operation which reduces the operating temperature of the lamp and increases lamp life, and further including an opening or vent adjacent to the fan which functions to reduce the fan temperature in operation thereby increasing the operating life of the fan.
