48" Depth

[Jdavison911]

Ok everyone I am in the process of designing our next tank and I am looking for a light that can get down to 48". Yes I do know the chances of getting something to grow down that deep may be impossible but I'm am going into this build knowing this. This tank is going to run 28" for 6' then it's going to drop down to 48" the last 2'. I see a ton of LED's running at 50% on what I would assume would be a normal depth of 25-30". Any ideas! Thanks in advance.

possible put 40 degree lenses on the leds. That should help pentrate. Are you making a drop off tank?

Thanks and yes that's the current plans. Going to get the tank put in auto cad and check to make sure all points can handle the water volume, almost 500 gallons. Hadn't thought about a narrower lens, thanks for the idea. I might just throw something together 48" and experiment with that.

With enough CREE XM-L LEDs running narrow lenses I bet you could light it no problem. Prob have trouble with SPS that deep but I'm sure something would grow.

Thanks Evan. Are you running Cree lights?

I have a couple DIY CREE setups I bought from rapid LED. The XM-L LEDs are about 5 watts a piece and I can tell you they are no joke. To give you an idea I have 6 cool whites over my 30 gallon freshwater tank and it is more than enough. My other setup is over a 20 gallon reef and it has only 4 cool whites. You'd need a lot more of the blues/royal blues to balance it out between whites and blues. I would call rapid LED and I'm sure they could help you out setting something up.
