Abstract: An adjustable overhead lighting fixture having fixed elongated support runners, which themselves may or may not be lighting fixtures, and a plurality of elongated hanger fixture elements which endwise releasably engage and span any two support runners at any point along the length of the runners and which are electrified from the runners. Hanger fixture elements may be used to support and electrify other hanger fixture elements such that the fixtures can be arrayed overhead to meet a variety of lighting applications.

Abstract: A long, linear indirect lighting fixture of a relatively small cross-sectional dimension which is mounted above eye level is comprised of lamps secured within an elongated housing, and a reflector and side lenses which direct and refract the greatest portion of luminous flux from the lamps above the horizontal plane of the fixture, yet a small portion of the luminous flux below but near the horizontal plane. The portion of light directed below but near the horizontal plane, which is controlled by, among other things, the relative placement of the lens and lamps, is great enough for an individual to have a perception of seeing a light source but small enough to avoid discomfort produced by glare.
