A lamp driving system that includes a first impedance and a second impedance coupled to the secondary side of a transformer, where the second impedance has a phase shifted value compared to the first impedance. Two lamp loads are connected in series together, and in parallel to the first and second impedances and to the transformer. The phase shift between the impedances ensures that the transformer need not supply double the striking voltage to strike the series-connected lamps. A difference in the resistance between the first and second impedances ensures that the lamps ignite in a specified sequence.
