The purpose of this project is to evaluate a newly designed, elevated, high-intensity runway edge light using a 100-watt lamp as its light source, rather than the standard 200-watt lamp, to determine if the lower wattage lamp and fixture combination would be satisfactory for category I and category II low-visibility operations, where a Federal Aviation Administration Specification type L-862 runway edge light fixture would be required. Pilot opinion during flight tests indicates that an installed group A version of the experimental runway edge light unit is visually adequate for category I weather operations and should be adequate for category II operations. Group A lights, however, did not meet the Office of Airport Programs Specification for L-862 runway edge lights Advisory Circular 1505345-48. An improved group B version will meet both requirements, since it satisfactorily passed the L-862 photometric specifications. This is the final report of a series that includes the following two interim reports 1 FAA-RD-74-128, Evaluation of an Experimental Elevated High-Intensity Runway Edge Light, and 2 FAA-RD-74-171, Evaluation of an Experimental High-Intensity Inset Runway Edge Light Fixture.
