EVALUATION OF OVERHEAD SIGN BACKGROUND MATERIALS AND MERCURY VAPOR SIGN LIGHTS. FINAL REPORT

Overhead Guide Signs can be illuminated to sufficient target value and uniformity with certain 100 watt mercury vapor lighting units. Coating materials based on thermal setting polyester, and thermal setting polyvinylidene fluoride have been found to be satisfactory coating materials for Overhead Guide Signs. Liquid Urethane Acrylic, sign enamel, thermal setting polyester and reflectorized sheeting have been proven as satisfactory materials for refurbishing deteriorated porcelain-enameled aluminum Overhead Guide Signs. Preliminary field evaluations and legibility studies indicate that approximately 40% of the Overhead Guide Signs in the State would not require illumination if the legend is reflective.
