Quote from: lights*plus on November 29, 2020, 12:01:40 AM The listing already ended. In the title & description the seller said Photography lamp. Was this self ballasted for 200-250 volt mains? Since this lamp says “MBF/U” on the etch, it needs a ballast to operate. It can be used on any 400w MV ballast in the world including US 400w H33 mercury vapor ballasts. “ML” means self ballasted mercury vapor in European terms.

In a universal sense that indicates the required OCV for starting the lamp. Normally, the 200-250v indicates that it needs a 200-250v mains series choke. For all choke ballasts, the OCV is the same as the mains supply.
