Abstract
A lamp is disclosed comprising a light source, an outer glass envelope having at least one dimple, a metallic base having at least one dimple, and a plastics skirt having means for complementary engaging and fastening to each of the dimples of the glass envelope and of the metallic base. The complementary engagement of the plastics skirt to the glass envelope is accomplished by snap-lock ramp-like extensions that fit into and engage an inner portion of the dimples of the glass envelope.
