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.
