Photometric Studies of the Austin 'Moonlight' Tower Lighting Systems
The Texas Highway Department, and 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. The study constituted one step in the high-level lighting phase of Research Project 2-8-64-75, 'Supplementary Studies in Highway Illumination'. (Author)
