Abstract : This report is an evaluation of red electroluminescent lamps, using the best obtainable lamps from numerous manufacturers. In the majority of cases, green phosphors were used with color conversion layers to obtain aviation red light. A number of tests were performed on the lamps, such as: brightness, color, current drain, voltage and frequency effects, life, high and low temperature exposure. The data were used to determine several characteristics of the electroluminescent lamps. The results indicate wide variations between manufacturers in overall lamp characteristics. (Author)
