ABSTRACT OF THE DISCLOSURE A fluorescent tube (10) supported at both ends in a respective base (15, 16) is surrounded by a transparent guard tube (1), which is closed at one end by a cap (2) having suspension hooks (3) and at the other by a handle (5) having a connection cable (7). A circuit board (24) having an ignition and feeder circuit arrangement is mechanically releasably connected with both the base (16) on the end toward the handle and with a closure element (28) disposed in the end area of the guard tube (1) toward the handle, this releasable connection being effected by holding devices (22, 26; 29). The closure element (28) is latched into the guard tube (1) by means of a detent spring (30). Contact pins (13, 14) and the connection cable (7) are connected to the circuit board (24) in a plug-insertable manner. The fluorescent tube (10) together with its bases (15, 16) and the associated circuit board (24) with the closure element (28) accordingly embody a mechanically coherent structural unit, which is easily pulled out of the guard tube (1) in order to change the fluorescent tube (10). No tool is required to accomplish this. Furthermore, to accommodate fluorescent tubes (10) of various types or dimensions, only the length of the guard tube (1) and the components inserted into the circuit board (24) need be adapted.
