ABSTRACT:
A light fixture includes a primary double arcuate buttocks-shaped reflector facing either a secondary double arcuate buttocks-shaped ("baby's bottom") reflector or a sieve-like reflector with lateral heat fins with a bulb therebetween. This system of reflectors emanates a large percentage of the visible light while absorbing a substantial percentage of the radiant energy and dissipating this radiant energy through the metal frame of the light fixture. The bracket for the socket for the bulb includes two parallel slots, perpendicular to the reflectors, to allow the bulb to be positioned between the reflectors.
