Abstract: A compact fluorescent sign light unit includes a ballast, a flat backplate and a socket for receiving a fluorescent tube, such as a twin tube lamp. The ballast has a substantially flat backwall, attachment devices for rigidly attaching the ballast to a support, and electrical connectors for connecting to an electric current source. The backplate has a forward surface rigidly attached to the backwall of the ballast. The socket is attached to the forward surface such that the fluorescent light tube extends substantially perpendicularly away from the forward surface, above a part of the ballast which is not covered with the socket.
