PCT No. PCT/DE92/00645 Sec. 371 Date Feb. 1, 1994 Sec. 102(e) Date Feb. 1, 1994 PCT Filed Aug. 4, 1992 PCT Pub. No. WO93/04569 PCT Pub. Date Mar. 4, 1994.A device for operating a gas discharge lamp (11) which is triggered by pulses which are transmitted by a starting device (14). In order to isolate the electrical components of a ballast (12) or a power supply apparatus (10) during the starting process, a reactor (13) which is constructed as a saturable reactor is provided in the ballast. The inductance of the saturable reactor is reduced by the operating current flowing after starting of the lamp (11). The device according to the invention is particularly suitable for starting high-pressure gas discharge lamps, the starting power of the lamp (11) made available by the starting device (14) being made virtually completely available.
