Abstract
A method of aligning and gapping arc lamp electrodes is to form a single piece electrode preform with a number of breakable junctions formed therein. The single piece preform is then positioned in the lamp envelope and sealed in place. The central portion of the preform is then removed by causing the breakable junctions to give way. The central portion is then removed from the enclosed lamp cavity, and the lamp sealing is finished by known methods.
