Abstract
An apparatus and method for thermally controlling a light fixture contemplate the use of a housing for holding a high-wattage, heat-producing lamp, with the housing having an opening through which light emanates from the lamp. Two lenses are provided, and mounting means support the lenses in spaced layered relation so as to form a thermal barrier that at least partially encloses the opening of the housing whereby the lens furthest from the heat-producing lamp is maintained cooler than the lens closest to the lamp.
