LED fixture with 100W pods

I'm thinking I might make one of these for my tank, and if it works out, I might build one for a few of my customers' tanks
You can also get the chips in multi-spectrum, and 50, 30, 20, and 10W chips.

 

That's a very good point. I would think it would be much easier to cool multiple 20 or 30W LEDs. The question is, is it worth it to get multiple large pods instead of just doing your 'standard' individual chip array like everyone does.

Blue Moon Aquatics has the P50 and P100 that use chips similar to these I'm guessing, and I don't recall that they had active cooling, but I do remember they had huge heat sinks, and those are probably the ones that aren't commercially available. Hard to believe that you wouldn't be able to find one like theirs in this day and age though.

 

There are links on the page under my first post link but here's a few.

That'll keep you busy...

 

Go to Steve's LEDs for them. I just checked his site out and he is now carrying Philips Luxeon LEDs which are better than Crees and less expensive

 

When I was planning out my LED array (which i never made) I was told that for a 120 gallon (2' x 4' and 2' tall) that I would want 72x 3W LEDs for a tank that was soft corals, zoas, etc. Then 96 LEDs if I wanted to have SPS corals, and if I wanted to have a LOT of SPS corals, I might go as high as 108.
Assuming a 20-24" depth, surface area is the key. Mine is 24 x 48 = 1152. Divide by 16 (one LED per 4x4 area) and that's 72 LED. Divide by 12 (3x4) and that's 96. Divide by 10 and that's 115. So take the surface area and divide by 16 for softies, 12 for mixed w/SPS, 10 for high SPS.
Hope that helps. I can't claim to be the expert but that's what I've been told.
As far as mixture of white/blue/other, that's a whole other discussion...
So +1 on what B-Rad said, you need at a minimum 2x that many LEDs
Anyone else can feel free to jump all over me and correct me. This is just what Matt N / ninja told me when we were going in on the LED group buy through TheFishMan65/RC via Cutter.

 

It appears I am waaaaaaaaaaaaay behind on this idea

Forget about Cree. Check out Philips Luxeon at Steve's LEDs:

Better and cheaper.

 

I exchanged a few e-mails with Steve from Steve's LEDs, you can just go through the contact us link on his site and he will get back with you. Probably best to get it from the horse's mouth.

Steve's is a distributor, most others are middlemen, so he can select the best bins and sell them for a better price. Philips LEDs generally use less Vf for the same output meaning they are more efficient = less power for same light. From what I've read, Cree is just really good at marketing, not saying they're bad my any means, they are definitely up there with the best of the best, but that doesn't mean someone else isn't better.

But hey that's me, I cheer for the little guy and go against the grain...

 

Bwahaha! I have one of these on the way to me!
