ABSTRACT:
The cover for the fixture comprises an opaque base having a cylindrical outer wall formed with a slightly lesser-diameter neck terminating in an outward-extending bead. Fitting on the base is a translucent cover having a truncated conical top and a cylindrical wall of the same diameter as the base. The rim of the cover wall has an inward extending bead and a groove inward of the bead. The beads of cover and base interfit to prevent separation except at one location where the base bead is interrupted and there is a slot in the outer wall for a blade or coin to be inserted to pry the cover off. The cover and base are of impact-resistant, slightly flexible plastic. Within the base is a metal mounting for a ring-type fluorescent lamp and its ballast and starter and also a fitting for mounting the base on a wall or ceiling or on an adapter to fit on a pole.
