1. A fluorescent lamp assembly, comprising:
- a fluorescent lamp having contact pins;
an adapter including;
a tip contact compatible with an electrical socket, a threaded ring contact compatible with the electrical socket and capable of being installed in the electrical socket by rotation of the lamp assembly relative to the electrical socket in a first direction, and keyhole slot receptacles;
a fluorescent ballast having input electrodes in electrical contact with the tip contact and the ring contact, respectively, and output electrodes for removably receiving the contact pins of the fluorescent lamp, wherein the keyhole slot receptacles are adapted to receive the ballast input electrodes in a bayonet style connection; and
a locking tab for preventing relative rotation between the ring contact and the electrical socket when the lamp assembly is rotated in a second direction opposite the first direction.

Abstract
A fluorescent lamp includes a ballast releasably connected to an adapter in a bayonet style connection. The adapter includes a locking tab for preventing removal of the adapter from an electrical socket once the adapter has been installed in the electrical socket. The fluorescent lamp has a lamp tube. The lamp tube is preferably connected to a base in a manner to minimize the total height of the fluorescent lamp. The lamp base is preferably provided with a recess in which contact pins are connected to the lamp base. The lamp may be directly connected to the ballast. The lamp tube may be arranged in a coil having a greater radial outer extent than the base or than the ballast.
