Abstract

A refrigerator cabinet light fixture assembly comprising an elongated base with an electrical socket at each end thereof, an elongated bulb supported between the sockets, and a clear plastic tubular sleeve concentrically supported about the bulb for defining an air insulating space therebetween. A plurality of stabilizing members are mounted on the base member intermediate the ends of the tubular sleeve for engaging the tubular sleeve and preventing relative movement between the sleeve and bulb for enabling the sleeve to protect the bulb from damaging impact of forces striking the exterior of the sleeve. The stabilizing members each have a base fixed to the light fixture base member and an outwardly extending sleeve engaging arm mounted for pivotal movement between an operative tubular sleeve engaging and retaining position and a retracted position out of engagement with the tubular sleeve for permitting removal of the sleeve and bulb from the fixture.
