Abstract: Fluorescent lamp assemblies with screw-in bases and solid-state ballasts, useful indoors or outdoors, such as in reflector spotlight or floodlight or table lighting. A two-piece non-conductive housing is retained simply by a pair of screws or the like, and laterally surrounds a fluorescent lamp assembly and its ballast, and also has a ratcheting screw-in Edison base on one end and a lens covering the light-emitting opposite end. Families of such lamp assemblies with different wattages and/or different beam-spreads are suitable for such usage, and for use in canister-like ceiling or wall fixtures.
