Abstract: A fluorescent lamp having a plurality of columns positioned in a generally uniform manner within the lamp envelope, each column having an electron emissive cathode mounted therein connected to a cathode leadwire. An anode member connected to an anode leadwire extends to the upper portions of each column. A conductive starter member is mounted within each column so as to provide a first gap between one of its ends and the cathode and a second gap between the other of its ends and the associated anode extension. A D.C. voltage is applied to the anode and cathode leadwires, the D.C. voltage being obtainable from an external A.C. source via a suitable voltage rectifier/multiplier circuit which is positioned within the re-entrant stem member of the lamp.
