ABSTRACT:
Combustion flashlight lamps for high-voltage ignition, in which two current conductors in the lamp envelope debouch on the surface of an insulating member, have an ignition mass which is provided on the surface of the insulating member and connects the current conductors, which mass contains 60-90% by volume of metal powder and 40-10% by volume of KClO.sub.4.
The metal powder consists of zirconium or a zirconium containing mixture. KClO.sub.4 may be replaced fully or partly by another oxidation agent.
The lamps have readily defined chemical properties, which after ignition are different from those prior to ignition, and are suitable for being incorporated in a series arrangement in flash devices in which a flashed lamp serves as a make switch.
