1953/1959 Elmer Fridrich developed the first halogen tungsten lamp prototypes with Emmitt Wiley. The first test use of the lamps were on aircraft wingtip lighting in 1955. The team later developed the double ended halogen lamp in 1959. Fridrich also pioneered electroluminescent lamp technology in the same period. Fridrich continued to develop improvements in the lamp until his death in 2010. General Electric. Nela Park. Cleveland, Ohio
