![]() One of my 250W ballasts is made by Phillips and it is labelled M58/H37 so it is both a 250W MH ballast (ANSI M58) and a 250W MV ballast (ANSI H37). Does this make it a "combination" ballast and if so what is the implication of using this ballast to fire Iwasaki's??
:confused: Is this a question for Iwasaki maybe? |
