ABSTRACT:
The present invention is directed to a improved gas discharge lamp particularly for use as flash bulbs or lamps, wherein two tungsten electrodes are fused into a glass tube. In order for the lead to be soldered to an outer end of each of the tungsten electrodes with a soft solder, the outer ends of the electrodes are provided with a coating of a refractory solder, such as a hard solder or brazing compound. The coating, which has a melting point approximately at the point of fusion for the glass tube, can be applied during the step of fusing the electrodes into the glass tube.
