Did you use netting over the tank, cut the photoperiod, raise the light higher, or do anything along those lines to acclimate the corals to the new light? That new fixture's about 3-600% stronger than your old light, if you just swapped them and left everything else the same you're going to end up with a lot of bleached or dead corals...
I wouldn't trust the percentages on the whites and blues as far as what they say on the light, those things can really pack a punch even at lower levels when compared to pc's, might want to turn them down even lower until your corals start looking ok again.
