A fluorescent lamp apparatus according to the present invention comprises a base member, a fluorescent lamp, and lighting means. The base member is a hollow member having a threaded base which can be screwed into the same type of socket as is used in ordinary incandescent lamps. It has a partition wall, and is divided thereby into a circuit chamber and an air chamber. The circuit chamber is located close to the base, and the air chamber communicates with the atmosphere. The lamp is attached to the base member, and comprises a tubular envelope, a pair of electrodes, and a mercury-vapor pressure adjusting means. The envelope is bent in shape, thus forming a discharge passage of a predetermined configuration, is sealed in an airtight fashion, and has both ends located close to the base member. The electrodes are contained within the end portions of the envelope. The mercury-vapor pressure control means incorporates a quantity of amalgam which is held within the air chamber of the base member, and is designed to supply mercury vapor into the envelope. The lighting means is located with the circuit chamber of the base member and is electrically connected to the electrodes of the fluorescent lamp, for lighting the lamp.
