12V DC Fluorescent Lamp Circuit Schematic Diagram

This is a circuit diagram of 12V DC fluorescent lamp for those who look for Fluorescent lamp driver using ordinary transformers. The transformer used is a step-down transformers from 120 to 6V in reverse, so that with primary voltage 12V could produce 350V for output. This voltage is used to turn on the fluorescent lamp without heating the filament. Take note that heat sink should be used on Q1, and be careful of the electric shock from the output voltage!
