The power-saving lamps generally comprise a screw base with built-in electronics and a lamp body which is connected thereto, is mounted on a lamp stand and has one or more discharge lamps. The screw base (1) is designed with a prismatic body (11) which is connected in one piece to the screw part (2) and has two parallel walls (12, 13) situated opposite one another. In each case one groove (14, 15), which is directed toward the screw part (2) in an axially parallel direction from the top side opposite to the screw part (2) and has an end catch (16, 17), is located in the said parallel walls (12, 13). The lamp stand (3) is designed in the same way as the body (11) and with the same prismatic contour. It is provided with two axially parallel tabs (31, 32) which are congruent with the grooves (14, 15) and have a latching lug (33, 34). A sliding sleeve (4) is provided, which has a cavity which is congruent with the contour of the body (11) and with the lamp stand (3) and, having been pushed over the body (11) and the lamp stand (3), retains the tabs (31, 32) with the latching lugs (33, 34) in the groove (14, 15) and the end catch (16, 17). The discharge lamp can thus be exchanged using the same connection base, with the result that reusable electronic components do not also have to be included in the event of disposal.
