Abstract
A task lighting fixture is provided for concentrating illumination on a work area beneath and offset to the side of the fixture. To accomplish this, an open reflector having a specular surface is mounted above and off to one side of the area to be illuminated. Transverse parallel vertical cross sections of the fixture are identical and comprise short and long compound curves joined together to form a cusp. The long compound curve extends toward the work area on which the illumination is to be concentrated. A U-shaped fluorescent bulb has each leg parallel to the cusp and the axes of the legs each are located on lines dissecting the cusp of the reflector.
