ABSTRACT: In a circuit arrangement for starting and oper- ating a high-pressure gas discharge lamp having an outer starting electrode connected to an igniter according to the invention, a full-wave rectifier (1) is present which is connected to an alternating voltage mains (A, B) and whose output is shunted by a series arrangement of a diode (4) and a capacitor (5), which is discharged in part after each half period of the mains alternating voltage through the lamp (3), a resistor (6), which is high-ohmic with respect to a current limiter (2), being included in the current circuit between the end of this capacitor (5) fac- ing the diode (4) and the lamp (3). As a result, the process of starting the lamp is facilitated.
