How many Cree 3w LEDs for my ADA 60P?
Hello,
First and foremost - I am sorry for all the LED questions! It sounds like I am going back and forth but I just really want to be sure that what I have will be good.  I have an ada 60-P (17.4g) tank with dimensions of 24'' long, 12'' long, and 14'' tall. My lighting situation is "unique" in that I have very little room for placing the light above my tank. At most, the fixture could be around 4'' above the tank. I am going to have clams and SPS (connected to a 20g sump for stability) so I will need quite a bit of light. The ratio I am going to use is pretty much 1 Blue to 4 Neutral White to 8 Royal Blue. I am planning on having this setup be dimmable (at least for the whites and possibly for the others). My questions are:How many LEDs would you suggest? I was originally going to buy 24 but now that seems like a bit much - but maybe it's right for this setup? I am now thinking of maybe 12, 14, or even 18. I am going to keep some low light corals (mostly zoas and rics) with this, so I do need some areas with low light. Would it be a good idea to concentrate the lights together in the center a little more than usual? Would you suggest I have no optics or 80 degree optics? Anything else I need to know? Thanks! |

Bump...Any ideas? I am hoping to get my LED fixture up and running fairly soon.
 I'm hoping it would work with ~14 because that saves me the most money but I don't want to skimp out on lighting.

20 with no optics will work great

I have 36 on mine. It is overkill. 20 would be fine. No optics is good for blending but will let light flood into the room...
