A lighting dimmer for controlling the current through a lighting load includes circuitry for applying a predetermined dimming level control signal to a control circuit in response to the absence of a dimming level control signal and the cycling OFF and ON of a circuit breaker. The dimmer further includes voltage compensation circuitry for maintaining a constant lighting load current notwithstanding short-lived changes in nominal line voltage.
