A fluorescent lamp unit adapted for use in an incandescent lamp socket includes a tube, a cap member having a base wall in which the tube is fixed, and a ballast housing having a primary cavity which is substantially defined by a circumferential wall and closed toward the cap member to create a secondary cavity which thermally isolates the tube from the ballast. The housing further includes a partition which isolates conduits for the wire leads from the primary cavity and each other, whereby uninsulated leads may be used. A potted ballast completely fills the primary cavity to improve heat dissipation through the circumferential wall.
