I've been using an inverter from one of those 12V fluoro lights that are powered by a car cigarette lighter for about 6 years now without even a tube failure. These lights are very cheap and I use a simple 12V power supply for it. Regards Tony Just when I thought I knew it all, I learned that I didn't.
