A full-wave electronic inverter generating a frequency of from about 20 kHz and 100 kHz for supplying one or more low-pressure gas discharge or fluorescent lamps. Said inverter is protected by a small tubular-core saturable transformer which has the inductive reactance necessary and sufficient for deflecting thewaves which are at a frequency higher than the frequencies stipulated by design and are produced by said lamps at the end of the service life thereof. The small inverter, in the primary winding thereof, prevents the waves from being introduced into the secondary windings, thus avoiding the oscillation of the inverter and energizing the condensers of the circuit thereof, this latter being a phenomenon which enables the situation in which, although the inverter is still being connected to the supply circuit, the inverter does not consume energy, even though said lamp or lamps is/are connected to the circuit thereof, until said lamps are replaced with new lamps. This inverter has a manual starting button, of one position, which is used to operate the inverter in a normal manner with new lamps.
