So I have this light and it's a 1000w MH bt56, can I change to the small bulb or will that ballast only work on bt56 bulbs

I got a 1000watt BT-56(The size of a football),and it will fit sockets but no commercially available hood.We probably got them from the same idiot vendor who knew what he was doing and screwed us.They will work with any 1000watt MH ballast.I am currently making a rather large air-cooled hood to fit this sucker.I would get a smaller bulb.They will be easier to work with and probably put out less heat.I'm just determined to see how big i'll have to make a hood to fit a football.Good luck.
