Abstract The invention relates to electric lamps and particularly to tungsten halogen electric lamps. More particularly the invention is concerned with tungsten halogen lamps with safe electrical disconnects. An efficient and safe lamp with a tungsten halogen capsule may be formed by using a two stage pyrophoric fuse as part of the electrical path to the capsule. The thin walled lamp with tungsten halogen capsule and two stage pyrophoric fuse yields a more efficient, less expensive and yet still safe tungsten halogen lamp. The thin walled lamp with tungsten halogen capsule and pyrophoric fuse provides a safe, thin walled outer envelope tungsten halogen lamp, provide a lamp with an oxygen sensitive fuse operable in low wattage lamps, provides a method manufacturing a pyrophoric fuse sensitive to moderate temperatures, provides an inexpensive and practical, low wattage, thin walled tungsten halogen lamp with a pyrophoric fuse.
