Abstract
An electronic control (1) for a discharge lamp (D), which is arranged to be connected to a source of alternating current (L,N), having a source frequency, the control having a first and second terminal (J,K) for supplying an electrical power output to operate the lamp; a capacitor (T) is in series with the first terminal, having a capacitance sufficiently small to limit a current flow from the first terminal at the source frequency of less than 30 mA.
