Abstract: A collar includes two sections that join together in an adhesive-less manner to form an aperture, an arm with a distally-located pawl extending from a base of each section, a frame on the other section at a position corresponding to the arm, a lower clamp located on the sections, an upper clamp including a distally-located projection extending from the base surface, first and second flexible clamps located at opposing ends of the aperture. A gas discharge tube lighting assembly includes a discharge tube collar, a discharge tube having a stem assembly with a first portion fitting within the discharge tube and a second portion having a seal ring with a diameter greater than the discharge tube outer diameter, the collar and tube connected by adhesive-less mechanical forces exerted on the upper, lower, and first and second flexible clamps with the discharge tube located partially in the aperture.

Abstract: According to some embodiments, a light cover has an axis extending vertically from a threaded base portion to an end portion opposite the threaded base portion. The light cover may include a vertically open, pear-shaped first half portion (e.g., formed of plastic). The light cover may further include a vertically open, pear-shaped second half portion coupled to the first half portion to form a cavity to hold an illuminating bulb portion of a compact fluorescent lamp. The first and second half portions together may form an outer surface contoured substantially in the shape of an incandescent light bulb.
