Abstract
An electric lamp having a light source, glass envelope made of a lead free glass, electric leads, and contacts, is disclosed. The compositional range of the envelope glass may be used in existing lamp manufacturing equipment, and otherwise substantially meets the manufacturing and product requirements normally met only by lead glass. The resulting lamp product has the same cost, and product performance, but now has the environmentally desirable feature of being lead free.
