A discharge lamp for connection to an associated alternating current power supply. The lamp is provided with two main electrodes and a starting electrode. Two diodes are connected in series, in cathode to anode relationship, between one associated AC power conductor and the starting electrode. In parallel with the diodes is a first capacitor. Connected to the junction between the diodes is a second capacitor which is connected on the other side thereof to a conductor from the other AC power conductor to the main lamp electrode remote from the starting electrode. In operation the second capacitor substantially changes its capacitance responsive to the temperature present with the lamp to effectively make the voltage doubler inoperative. |
