Abstract
Flush and pump flush processes yielding light sources for incandescent and metal vapor discharge lamps are disclosed. The flush and pump flush processes also yield lamps that are particularly suitable for deposition of a reflective coating on its outer surface. For such reflective coated light sources, the associated lamp leads are encased in glass and therefore are protected against any deleterious reactions that may otherwise result from the deposition of the reflective coating process. The light sources yielded by the flush and pump flush processes of the present invention are advantageous in reducing the mounting arrangement of the lamps in which the light sources are housed.
