Abstract
A single-ended compact fluorescent lamp having an envelope that is partitioned or of multi-U-bent shape and defines a tortuous arc path is combined with a plug-in ballast module which is elongated in a lateral direction but has a low profile and a narrow width. The resulting decrease in the overall height dimension of the unit formed by the mated lamp and module, together with the narrow width of the module, permit the unit to fit within the harp component of a table lamp or similar lighting fixture and be used as a replacement for an incandescent lamp. The screw-in socket of the lamp fixture is provided with a threaded adapter plug which enables the lamp-ballast unit to be plugged into the adapter after it has been inserted between the spaced support rods of the harp component. Alternatively, the threaded plug is made a part of the module and constitutes an integral threaded base member which permits the lamp-ballast unit to be screwed directly into the fixture socket after the harp component has been temporarily removed.
