Shelley, from what I read, the AI comes in the SOL white and super blue. The difference is that each has a different range of color. I believe the other features are all the same.
For me, I would be using my Apex to run them, so whatever that does, is good, I suppose
My concern tho, is on my tank, I figure I've got a rectangular area containing corals about 18" x 60"ish. Are three of either good enough for this area, with some corals being 24" deep.
Some site I read compared the AI to a 400w MH, but AI's site doesn't mention that anywhere I can see.
