An apparatus for supporting a primary lamp and a secondary lamp is disclosed. The apparatus comprises primary and secondary brackets, and primary and secondary sockets. The primary socket is affixed to the primary bracket, and receives the primary lamp, preferably a high intensity discharge lamp. The secondary bracket has a first end affixed to the primary bracket and a second end. The secondary socket is affixed to the secondary bracket, and receives the secondary lamp, preferably an incandescent lamp. The primary bracket defines a projected perimeter. The second end of the secondary bracket is normally biased to an operating position where the secondary lamp extends outside the projected perimeter of the primary bracket, but can be moved to a maintenance position where the secondary lamp is within the projected perimeter of the primary bracket. In operation, the secondary lamp is thus spaced apart from the primary lamp. During lamp replacement, however, the secondary bracket can be moved to a position where both lamps can be extracted from their enclosure.
