ABSTRACT:
An arc discharge lamp assembly simulating the appearance of a gaslight for installation in an existing incandescent light fixture. The assembly includes an arc discharge lamp having electrical contact means (e.g., a pair of contacts on the base of the lamp) located at one end thereof. A mantle supported by a wire frame substantially encloses the arc discharge lamp. In a preferred embodiment, the lamp includes at least two longitudinally extending leg members having a predetermined spacing therebetween and joined together by a transversely extending envelope portion. A diffusing means is disposed adjacent the leg members to provide an appearance of a substantially uniform light output from the entirety of the envelope during operation of the lamp. Preferably, the assembly further includes an adapter having a housing which contains a ballast and has a screw-in, incandescent-type base projecting from one surface thereof and a pair of contact receiving means on another surface thereof for mating with the pair of lamp base contacts.
