Dear oh Dear, Did we hit a soft spot? I dislike bashing someone for spelling since as soon as you do YOUR spelling and grammar comes into question
BTW I don't feel Hijacked this is just more of the same topic. As for different ballasts and European to American power. Of course you'll get more light using an European one, your over-driving the ballast 50hz ~ 60hz. Much like over-driving NO fluorences, they get brighter and half there life. I'm going to do some serious research into ballasts & MH of the same wattage and compare the outputs.
I was really hoping to buy an industrial grade ballast (from work) and stick a proper bulb in the socket. An industrial bulb will be 2700K or 4500K . . . Little low. lol
