The purpose of this effort was to determine the suitability of a portable photometer to rapidly measure the light output of inset runway lights. The work involved 1 Laboratory measurements to compare the experimental unit with a standard laboratory photometer 2 Field measurements of inset lighting by a team of technicians and 3 Analysis of the photometer construction. The result of the tests indicated that the portable photometer was adequate for the measurement of L-850A inset lights, but that some minor changes should be incorporated in the final design to make the unit more rugged and to permit measurement of more than one fixture type.
