I'm setting up a 90 gallon megaflow as a reef now and what I went with was the Aqualight Plus Deluxe Lunar from Coralife. This has 4 X 96 watt PC
Bulbs ( 2 X 10,000K and 2 X 03 Actinics) and 3 blue lunar LED
's. It hurt spending the money for it, over $500, but I figured it would be cheaper in the long run to spend the money up front. Would have liked to go metal halide, but the budget wouldn't handle it right now. I have a regular Aqualight 36" PC
fixture on my 50 gallon ( 2 X 96 Watt) and have nothing but good stuff to say about it. The 50 was basically a FOWLR
when I got the lighting, but have since added an anemone and some shrooms
which are doing great. It does put out some heat, but has built in cooling fans that do seem to work well. Can't comment on the new light yet since the tanks not up and running, but I expect it to also do fine based on my experience with the smaller version. Coralife does make a 48" fixture that includes the Lunars and goes for right around $250 which should be adequate for a FOWLR
. Will only get you around 2 to 3 watts/gallon in a 90 though and would have to be replaced if you go reef. I looked at that option myself.
