Fluorescent lamps in the range from 4 to 40 W can be powered on from cells or batteries. The lamp will glow with less power depending on the supply. The circuit can be used in emergency light systems, camping and other applications. The transistor must be mounted on a heatsink. Transformer has a primary according the AC power line (any voltage between 110 and 240 V) and a secondary rated to 6 + 6 V to 12 + 12 V 300 to 800 mA. The correct values for R1 and R2 can be by found by experiments. The transistors must be mounted on heatsinks.
