Abstract
A fluorescent light fixture is provided to illuminate a rearwardly adjacent wall. An upper reflector reflects light from a forwardly offset fluorescent light bulb in a downwardly and rearwardly oblique direction to illuminate lower areas of the rearwardly adjacent wall. A lower reflector with an upper edge directed substantially toward a central portion of the fluorescent light bulb reflects light substantially horizontally to illuminate uppermost area of the rearwardly adjacent wall where the wall abuts the ceiling. A throttle plate controls the amount of lamp exposed to the lower reflector for intensity control. A glossy white series of reflective surfaces approximating an involute curve gathers output from the fluorescent light bulb for redirection from the specular portion of the upper reflector without hot spots or striping on the wall. The lamp is rotationally positioned to maximize the amount of output controlled by the optic system. A vertically adjustable mounting plate adapted to conventional grid-type ceilings formed by ceiling member rails is provided.
