ABSTRACT This invention provides a tungsten-halogen lamp having a thin-wire filament and a hydrogen-impervious envelope. Containment of hydrogen within the lamp envelope suppresses tungsten corrosion of the filament and prevents early termination of the lamp. In the preferred embodiment, an aluminosilicate glass is employed as the hydrogen-impervious envelope material. This invention overcomes a substantial impediment in the development of a feasible tungsten-halogen lamp as a replacement for the standard Edison-type lamp for general lighting purposes.
