An efficient, low operating temperature L-C ballast for a mini fluorescent lamp, wherein the ballast includes a capacitor connected in series with a transformer. The transformer comprises a primary coil and a shorted secondary coil. When used with a 4 watt mini fluorescent lamp, the primary coil should have 500 turns and the secondary should have 28 turns. Furthermore, the wiring used in the primary and secondary coils should be number 33 AWG wire. In an alternative embodiment, a resistor is loaded in parallel across the transformer. The resistor should preferably have a resistance ranging between 100 to 300 ohms.
