A portable fluorescent lamp including a DC to AC inverter powered by a conventional 12-volt battery utilizing a saturating-type switching transformer having a core which produces a square-loop hysteresis effect. An inductance is provided in the primary winding of the transformer which is connected in circuit with the inverter and a capacitor is provided in series in the secondary with the fluorescent tube. No special starter filaments are needed. The combination of the inductance in the primary and the capacitor in the secondary provide sufficient power for igniting the fluorescent tube while, at the same time, limiting the current through the tube after ignition.
