I must be missing something and I am hopeful someone will point out my flawed logic. It seems, that as long as I achieve the needed PAR level in the spectrum used to "feed" the zooxanthellae", which I believe is between 450-470nm range, then anything else is just for visual preference of the human observer. If this is so, then black box LEDs using CREE XT-E and XP-E2 or Bridgelux will grow the corals the same as Radion G6. I realize they may have some electrical and safety considerations, but it seems that the light wars are over hyped. Am I missing something?
