Abstract
Two or more fluorescent lamps having a total length of about 96 inches and each having a diameter of one and a half inches and consuming less than 10 watts power per foot of length are connected in electrical series combination, one cathode of each lamp being connected to that of another lamp. An end of each remaining cathode of the combination is respectively connected to one of a pair of input electrical power terminals for a 50 or 60 hertz a-c line voltage in the range of 200 to 300 volts, one of the latter connections being via a ballast inductor. A starter switch is connected across the other ends of the remaining cathodes, and a secondary winding on the ballast inductor is connected across the interconnected cathodes. The lamp designs are specified such that they will start and operate in the circuit from the a-c line voltage.
