For me it's because I only have LPS and softies and I don't want to torch anything. I think this is the case in the other thread. There didn't seem to be alot of feedback from SPS only tanks. I increased the white by 5% one day and there seemed to be alot of corals less than fully opened, could have been fine in a few days after an adjustment period but I have way too many corals to take the chance. There will always be a give and take regarding coral colors when switching lighting systems...some will look better some won't.
