Hi, I am a newbie living in Europe. I would like to build a DIY projector but don't have great experience with those HID lamps. I found a lot of bulb types specs but are all strange voltage! Does anybody have any experience with a ballast and a HID 575W that could be used in a 50Hz 220V system. I tried to search for a circuit for these lamps but could not find it. Is that similar to those that supply fluorescent lights? I apologize for the stupid questions but could not find this info in the forum with the search engine. Thank you!
