The end of cheap energy has forced a rethinking of effective lighting design. In a discussion of light sources, the author compares the design, operation and efficacy of incandescent, fluorescent, mercury, metal-halide and sodium lamps, particularly as they relate to highway lighting. The characteristics considered are wattages and efficency (lamps only), life, color rendition, light direction control and source size. In addition, comparisons are shown for relight time, fixture costs and operating costs.
