Hi, I just uploaded the 4w fluoro tube driver circuit that I reverse-engineered from that cheap night light. Perfect for a home built UV Eraser using a standard G4T5 4w UV tube. I also put up the other 4w circuit posted by Florian (hope you don't mind) and a novel 120v AC LED light circuit from a commercial traffic light solid-state bulb that was posted by Richard (at his request). They are here: http://centauri.ezy.net.au/~fastvid/tube4w.htm (note! there are photos and the page is about 200kb) :o) -Roman -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
