I want to power an Osram 250w mercury vapor lamp (I've attached the datasheet) from 220v mains or 24-48v DC. I do not want to use regular ballast (or self-regulated lamp) to avoid mains frequency flickering. Are there any rather simple schematics fot that out there? Ideally I would like to have power ajustment pot on the driver so I can use lamp at lower brightness.
