In a method for operating an electronic gas discharge lamp by a TRIAC circuit, a current is drawn from the dimmer circuit when the TRIAC is in a non-conductive state to bring the TRIAC in the conductive state and the current drawn from the dimmer circuit is reduced when the TRIAC is in a conductive state. According to the invention a substantially fixed current is drawn from the dimmer circuit in the conductive state of the TRIAC at a sufficient level to maintain the TRIAC in the conductive state. To this end a current control circuit for controlling a current drawn from a power source including a voltage controlled variable resistive switch circuit driven by a voltage control circuit.
