First I would use my Amprobe just to see if we have a bad connection which I'm sure you did. Next I would worry about the metal halides. Watts?
I used to warm up next to those things in the winter!

Bill A. another good answer in my opinion, I bet if he takes out just two halides on each circuit he will see a dramatic loss in temps on the high temp zone. But I still think it sounds like an bad conection prob. Hope he lets us know!
