In an attempt to quieten the voices whispering 'go bigger', 'vlamingi tang', 'looks crowded', 'vlamingi tang' ..... oh, wait, those were my kids :lol: Saw the ETM Gen4 Pro Radions at one of my LFS and decided to just get better lights. Out with the Reefbreeders Photons (which gave yeomen service BTW); in with Gen4 pro triplets. I've little illusions that they'll grow corals any better, but they certainly look better and perhaps will color up a few of my SPS that have been looking a little colorless. They also dim down better than any other LED fixture I have seen, and though my fish probably don't care, they should ... it's cool.
