Abstract
A lighting fixture for mounting from a suspensory surface, such as a ceiling, wall, or the like, includes a counterweight for balancing or equalizing the weight in the fixture resulting from a ballast being positioned within the frame of the fixture. The weight of the frame is adjusted to equalization relative to the ballast for proper alignment during mounting of the lighting fixture.
