An improved solid state electronic dimmer circuit for controlling the intensity of large electric lamps, such as theater and television lamps, in response to a low power DC control signal. The transfer characteristic of the circuit is determined by the properties of a generated precision waveform having a predetermined shape and amplitude and a fixed phase relationship to the power line voltage which, in conjunction with the DC control signal, determines the effective voltage at the output of a dimmer unit. The same precision waveform may be used to control a plurality of dimmer channels, thereby making possible precise matching of performance of all commonly controlled channels, and effecting significant savings in the cost of manufacture.
