Abstract: An electrical arrangement is disclosed comprising a circuit to supply current to a discharge lamp. The circuit comprises a lower voltage source of alternating current in the form of a square wave generator. The current is fed to two transformers, the primary windings of which are connected in series, the transformers being physically located immediately adjacent the electrodes of a discharge tube. The secondaries of the transformers are also connected in series, and are connected to the electrodes of the discharge lamp. Only extremely short high-tension leads are provided extended between the secondaries of the transformer and the electrodes. Each transformer is a transformer having a coupling factor in excess of 0.
