ABSTRACT:
A pulsed metal halide arc discharge light source comprising a hermetically sealed light transmissive envelope with an anode and cathode protruding therein and an emissive material including at least one recrystallized metal halide salt covering the cathode. There is no mercury in the emissive material. During an application of a short-duration electrical pulse across the anode and cathode in a preferred embodiment of the invention, bright colored light is emitted from the lamp, the color of such emission being determined in large part by the choice of the metal halide salt or combination of metal halide salts employed in the emissive material and the duration of the electrical pulse, and the temperature of the emissive material remains less than one hundred degrees Centigrade. A lamp in accordance with the invention is particularly well suited for use as a signal lamp, such as a navigational beacon.
