11+ Schematic Fluorescent Lamp Circuit Diagram Background. One filament evaporates and blackens the lamp, makes it electrically unsymmetric and shortens the lifetime. The 12v drivers for fluorescent lamps are tricky, because of the compromise between a good operating efficiency and the ability to start the lamp.
