ABSTRACT:
In a discharge lamp comprising a discharge vessel surrounded by an outer bulb filled with nitrogen, a hydrogen getter is used comprising more than 80% by weight of Zr and Co and one or more elements chosen from the rare earth elements. The getter effectively removes hydrogen from the outer bulb and is not poisoned by nitrogen.
