METAL HALIDE ARC LAMP HAVING GLASS CONTAINMENT SHROUD A double-enveloped lamp assembly includes a light-source capsule, which is substantially surrounded by a light-transmissive shroud made of glass, preferably aluminosilicate glass. In a preferred embodiment, the lamp assembly is a metal halide arc discharge lamp, and the shroud is a cylindrical, open-ended tube. For metal halide lamps having a power rating of 150 watts or less, the shroud preferably has a wall thickness of one millimeter. The thin wall glass shroud meets or exceeds containment performance requirements.
