Abstract
A light fixture for horizontal or wall task surfaces for office and like interiors adapted to be used with an ambient light system which fixture utilizes a plain rectangular elongated housing for a fluorescent lamp with simplified end brackets which permit the fixture to be mounted directly or indirectly on screens or partitions at any desired elevation, and providing angular adjustment. Direct glare is avoided and veiling reflections reduced by angular selection, lens selection, and recessing the lens within the housing. The adjustment brackets provide precise angular incremental adjustment but are designed to slip if excessive force is exerted on the fixture to avoid damage to the fixture, partition, or screen.
