Wow, that Aqua Illumination unit looks interesting.

Is there something Im overlooking in that review? I mean, my only complaint COULD be that I like a fuller spectrum, but its not really even that bad. You could pair it up with a couple T5s or something to bring up the actinic or something. But 88 watts to compete with the 250watt 20,000K XM? Thats getting better. When they hit the output of a 250wattDE 14,000K pheonix or Ushio, and only cost $500, I might have to bite.
I wonder if I can put one on my light rail... that would be sweet... my 125g lit with only 88 or so watts of LED and 216 watts of T5s. Lol. Id be growing SPS with 2.5 watts per gallon! If that doesnt destroy the Watts/gallon myth, I dont know what does... oh, wait, yeah... a skylight.
