I’ll answer my own question. I think a more likely scenario of our 5 year acro above is as @jda stated. I believed this to be the case immediately when reading the post, but the author indicated that the LED switch was undoubtedly the hero in this scenario. I am more inclined to believe a 5 year timespan without a crash, combined with a colony already becoming large to begin with are more reasonable explanations. Colonies do indeed grow exponentially with their size if necessary input is present. I think as long as an appropriate intensity of necessary wavelengths are provided, with appropriate coverage, any light source would have performed admirably in that instance. Ignoring nuances in color.
My gut puts my opinion more in line with Dana’s “there are no bad lights just bad application” statement“. I’m not going to sit here and insist there is a best. I’m not a successful enough aquarist to make those claims.
