![]() Most industrial lighting places sell a 250watt MH ballast. Problem is if you are using double ended bulbs most spec a M80 ballast (HQI) which is not made anymore in North America and u will only find used, or from overseas or electronic. Don't know why they don't make a M80 coil and core ballast anymore, but they don't. A regular 250 watt coil and core is ANSI M58 and are easy to find but typically only for single ended bulbs.
