ABSTRACT:
A dual reflector lighting system having a housing, a ballast and a lamp socket connected to receive a gaseous discharge or high intensity discharge (HID) lamp. An outer reflector is mounted to the housing to reflect a portion of light from the lamp. An inner or auxiliary reflector is mounted coaxially with the lamp to reflect a substantial amount of light from the lamp downwardly. The auxiliary reflector is preferably adjustable relative to the lamp. The invention also covers a dual reflector assembly, including an outer reflector and an inner reflector, adjustable relative to each other which is adapted to be mounted to a HID fixture. The invention also covers an auxiliary reflector having a predetermined size and shape adapted to fit within an outer reflector of a HID fixture and preferably includes facilities for adjusting the auxiliary reflector relative to the outer reflector. The invention also covers a retrofit kit which includes a ballast, an auxiliary reflector and facilities for connecting the auxiliary reflector to an existing HID fixture and for adjusting the auxiliary reflector so that a substantial portion of light is concentrated downwardly.
