ABSTRACT:
Incandescent lamps having an outer envelope with their outer surface sandblasted except at the neck section and the inner surface electrostatically coated are disclosed. The combination of the sandblasting and electrostatic coating provides the incandescent lamp with a diffused light output. The absence of sandblasting at the neck section reduces the breakage of the outer envelope at the region of joinder of the outer envelope to the base of the incandescent lamp.
