True, it is old but the amazing thing is there is not a whole bunch of discussions around it online. Sanjay Joshi seems to be the only one that has done any extensive research, he has published some really good articles. If you check other forums, there is mention of it but they don't go anywhere. I guess it's not as cool as the new LED trend, but overdriving MH bulbs with magnetic ballasts is interesting nonetheless.

In the case of some bulbs such as the radiums I run they fire to spec on hqi ballasts and aren't actually over driven. Not exactly going green using these ballasts but I love the output

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.

Might be time to pull out the screwdriver! Actually the newest AM ballast is the reflex cube, they are magnetic and manufactured in the USA but I don't know who makes them for AM. The one I am using is the Oceanballast dual 250.
From what I have been reading on RC it seems like the Bluewave 7 or Hamilton ballasts are the only way to get this true M80 ballast (PFO is out of business but worth a mention I guess), please correct me if I'm wrong.
