hmmm.. I was wondering why I saw a subscribed post I didn't remember reciently LOL
a M80 ballast (true magnetic M80) which is only made by Advance transformers (north american company) should be pulling around 400 watts with a 250 watt SE bulb a little less with a DE bulb, at 310 watts I would say they put a M80 starter and capacitor on a pulse start ballast and used that. will be a little lower output this way (well a fair bit actualy) I am not saying thats what they did but I have seen that done. the other thing I saw once was a european ballast converted to NA voltage (easy to do) this gives different out put as they are not a HQI ballast but are simular.
