A light fixture suitable for illuminating highway signage and billboards having large surface areas. The fixture includes a curved reflector assembly, shaped generally like a cobra hood that is attached to a plate disposed in a base. The reflector assembly 38 includes a plurality of spectral segments, integrally disposed in bands and rows of the reflector assembly so that an portion of the spectral segments is disposed above the plate, an intermediate portion of the spectral segments is disposed partially above and partially below the plate, and a portion of spectral segments is disposed below the plate surface. A lamp is supported within the fixture for facilitating projecting a substantially rectangularly shaped plane of light distributed in a plurality of substantially rectangularly shaped luminance patterns onto a flat surface. In one embodiment, an induction lighting assembly is utilized in cooperation with the reflector assembly to provide uniform surface illumination at relatively low energy usage rates. Retrofit kits, for upgrading conventional light fixtures, are provided.
