The present invention relates to a round garage light assembly having a housing with a lamp mounting surface wherein a main HID lamp and an auxiliary circular high output fluorescent lamp are mounted. The auxiliary lamp is mounted centrally within the assembly and above the photometric center of the high intensity discharge lamp so that the light pattern emitted from the auxiliary lamp is symmetrical and the auxiliary lamp does not shadow the light emitted from the HID lamp.

A light fixture comprising a rotatable housing, a mounting yoke and a mounting fixture for securing the housing directly to the top of a hollow post to permit the housing to be directed straight down or at a tilt angle to either side. The housing includes integral or insertable axle portions that protrude from either side of the housing. The top of each side of the yoke includes a support casting with an opening for receiving the respective protruding axle portions of the housing. Matching indicia on the end of at least one of the axle portions and the receiving casting hub provide degree of tilt information. Wiring from the power source coming out of the top of the post progresses through one or more appropriate channels in the yoke, through the appropriate casting and through an accommodated protruding axle portion. The yoke is preferably comprised of at least one tubular member. The mounting fixture in the form of matching top and base plates mounts the center brace portion of the yoke to the top of the post.

A multi-lamp HID luminaire is provided with a HID ballast. An ignitor that produces a high voltage ignition pulse is coupled to the HID ballast and is also coupled to a plurality of HID lamp sockets that receive HID lamps. A cycling switch is also electrically coupled to the HID ballast and causes a periodic power interruption to the plurality of HID lamp sockets.
