Michael, sorry missed the part where you said "there are more than a few posting they are ditching LED because they do not believe they can grow corals or produce colour"
I agree this is crap. LED grow coral just fine, and produce beautiful colors. Anyone ditching because of that is perhaps doing other things wrong.
I'm ditching because I can get slightly better color from other technologies. Not that LED didn't do the job, just didn't do it well enough for my personal tastes and my tank. As I said, for many tanks, LED may be the best solution!
