Here is the schematic of a simple fluorescent lamp driver circuit based on two transistors. The circuit uses capacitive ballasting for driving the tube. An 8 W standard fluorescent tube can be efficiently driven using the circuit.
The two transistors (2SC1983) with associated components forms a oscillator around 1KHz. The oscillator is wired so that saturation condition of the transistors are prohibited. This adds on to the efficiency of the circuit. The circuit produces a clean sine wave with very less noise.
