Abstract

Halogen bulb without additional safety device for high-volt/intermediate-t operation with a bulb pinched on one side produces an inherent safety effect by producing a current lead segment that is pinched from an uncoiled wire with a diameter of 130 .mu.m at most and the distance between the two current leads is suitably selected.
