ABSTRACT:
A pair of 48-inch long preheat fluorescent lamps, each one and a half inches diameter and consuming less than 10 watts power per foot of length, are connected in series with each other and with a ballast, for operation from 50 or 60 hertz a-c line voltage in the range of 200 to 300 volts. A starter switch is connected in parallel across each lamp. The lamp designs are specified such that they will start and operate in the circuit from the a-c line voltage.
