1. A variable load circuit for use with a lighting control device, which variable load circuit is arranged to operate with two different load characteristics during a half cycle of an applied alternating signal, wherein the variable load circuit comprises means responsive to the applied alternating signal arranged to allow current flow in response to voltage applied during one portion of the half cycle of the applied alternating signal, and to allow the variable load circuit to act as a constant current sink during another portion of the half cycle, wherein the variable load circuit is arranged to operate independently of any external load, connected to the variable load circuit.
