• Abstract:
  Through the cooperation of the city of Austin, Texas and the Texas Highway Department, the Texas Transportation Institute conducted a study of photometrics at the location of one of the 150-foot "moonlight" towers in Austin. This tower was equipped with six vertical burning mercury vapor lamps mounted in radial reflectors at uniform angular spacings of 60°. Photometric data were obtained for clear and phosphor coated mercury vapor lamps of 400- and 1000-watt type to determine the applicability of this simplified system to interchange "area" lighting. This study constituted one step in the high-level lighting phase of Research Project 2-8-64-75, "Supplementary Studies in Highway Illumination".
