PHOTOMETRIC STUDIES OF THE AUSTIN MOONLIGHT TOWER LIGHTING SYSTEM

PHOTOMETRIC MEASUREMENTS MADE AT A 150 FOOT TALL MOONLIGHT TOWER IN AUSTIN, TEXAS ARE REPORTED. FOUR TYPES OF LAMPS RANGING FROM 400 TO 1000 WATT MERCURY LAMPS, WERE TRIED. HORIZONTAL ILLUMINATION MEASUREMENTS WERE OBTAINED TO DETERMINE THE APPLICABILITY OF THIS TYPE OF LIGHTING TO INTERCHANGE AREA LIGHTING. THE AUTHORS FEEL THAT WHILE THESE MEASUREMENTS APPEAR QUITE LOW THE OVERALL VISUAL APPRAISAL WAS GOOD. THEREFORE, THE CRITERIA OF HORIZONTAL ILLUMINATION MAY NOT BE ADEQUATE. /BPR/
