This makes me want to upgrade my two Radion G1s with TIRs to the Pros. I have these over my 100 gallon mixed cube tank, and frankly, I have been very satisfied with the colors of LPS and soft corals under them. It has always been some SPS that don't color up to their full potential under Radions.
This is my experience only, but most montipora, stylophora, seratiopora, and pocillopora all do great colorwise under Radions, as good as any coloration under halides I have ever seen. It is mainly acropora and millepora species that I have seen that don't color up as well as they do under halides.
