Abstract: The system contains a quartz arc tube surrounding a gas tight envelope containing mercury, a metal halide, a rare earth gas and a pair of end to end spaced apart tungsten electrodes attached at a distal end to a molybdenum foil seal. A circuit is provided to generate an initial ignition voltage of 30,000 volts and thereafter, a circuit of 100-2,000 watts with a timer to automatically break and reconnect the circuit to provide a strobe light. A single driver actuates multiple lamps.

Abstract: The lamp has a borosilicate lens bonded to a gas tight envelope containing a protective gas. The envelope contains a high gloss reflective coating on an inner surface and has a bulb mounted on a pair of support posts. The bulb contains a coiled tungsten filament within a halogen gas tight envelope. The filament is axially connected on each side to a tungsten wire, a molybdenum foil and a protruding lead wire. Each lead wire penetrates the gas tight bulb envelope to an integral tulip shaped end portion of the bulb, each end portion enclosed by a brass end cap. A bore in the end cap permits an electrical conductor to be soldered to the protruding lead wire.
