Abstract: A lighting fixture to be mounted within a ceiling comprising a housing, a rotatable collar and a lamp mount assembly, for holding a lamp in place. The lamp mount assembly is connected to a portion of the collar with a pivot arm. The pivot arm pivots between a zero degree tilt and a maximum degree tilt. The lamp mount assembly is connected to the pivot arm with a hinge so that the lamp mount assembly may be tilted with respect to the pivot arm between an operational position and an inoperational position to provide access to a normally inaccessible portion of the lamp. The lamp mount assembly returns to its original position after relamping without disturbing the previous lamp beam settings or adjustments.

Abstract: In a ceiling supported lighting fixture, an improved mounting device is provided, having clamping plates with a notch for receiving a ceiling support member. The clamping plates are mounted to the end plates of the light fixture in two parallel pairs to effect alignment of the notch and plate, and the ceiling support member can be locked in the notch to prevent inadvertent relative movement. The locking is carried out by a latch member which is pivotally mounted on the clamping plate and moved between a locking and an unlocking position. The lighting fixture is also provided with an improved ballast holder including a ballast hole in a wall of the fixture and two identical ballast mounting clips, each formed from an integral blank of spring metal receiving an edge of the housing under tension and a spring clamp extending from the gap to hold a ballast in place upon insertion into the hole and between the two clips.
