The specification discloses a circuit for starting a plurality of fluorescent lamps. The ordinary fluorescent lamp requires a heavy inductance, usually referred to as a ballast, for starting the lamps. The ballast is heavy and expensive. A lightweight resistance could be substituted for the ballast, if a simple means could be found to start the lamp. The present invention uses a single transformer to supply a higher voltage of, for example, 180 volts, for starting and a switching arrangement for switching the transformer from lamp to lamp. After the lamps are started they are switched onto a standard line voltage of 120 volts, for example. Thus, a single transformer is required to light a number of lamps.
