Yes it should do 2 at 50W but if one drops off for some reason and theyre hooked in parallel you will get all the amperage through 1 array...meaning you'll lose both. Use fuses! I didn't look at the specs to see if it could be done in series though.
Bit out of my depth but i believe it Would have to be run parallel. I would run 2 100W LEDs in parallel at 50w NOT 2 50W LEDs through a 100w driver (for the above mentioned reason). By parallel I mean split the driver's positive and negative to each contact on the LEDs vs wiring positive to negative to positive, etc.
Can't wait to see OP's cooling solution as I'm not sure how to hang the coolermaster 612 and I like the look of the geminii much better...(ie. hurry up and build it!)

Have you decided what Lens you are going to use, and how are you going to dim them?

Yes at 50W each. You could do it that way. Seems odd to me but you could.

I did ask the ebay LED seller if he sells it in 14000K-18000K. I'll post an answer when he gets back to me.
If you had a shallow tank that was wide and deep you would want better coverage but penetration wouldn't be as important so 2 x 50w would be a better option. Personally I would use separate drivers though.
There is conjecture as to how much heat and how much light makes up the 100W but 50%-75% seems fair. To me the geminii s524 would be bare minimum. I may wait for you to build yours and see what your surface temp is before epoxying the chip to the heatsink

Sounds like what a 40Br would use!
The 100W led light is estimated to be at least 50% efficient so you need to cool somewhere around 50w at 100% load. Logic tells me that just about any decent $10-25 CPU heatsink with fan should be plenty. But...Since you only get to epoxy it once I'm inclined to go with something really big and not have to worry about maxing out fans. Very interested to see what op builds as I'll be one step behind him on mine (my stuff should be here in around 7-10 days I'd guess)
Those 100W LEDs come in like 3000k-20000k flavors on eBay.

Are there any comparables out there, in terms of intensity for this light? Is it like a 175w, 250w halide?
Ah. The burning question...what is it comparable too?
Let's agree (for the OP's sake and our sanity) that LEDs do work. My tank is personal proof of that (I have a 3W Cree LED array and color and growth is amazing). Basically, if you are one of the last 5 people on earth still grasping on the belief that MH's will always be best, no need to reply
My best guess and feeling is between 250W - 400W's of MH. Depending on the lense you use.

lol I too currently use LED's. I have the 120w 18K fixture by Reeffiltration, and my corals love it. I just am facinated by these more powerful ones.. and the fact that it's DIY!
That heatsink would work I'm sure...still our of my comfort zone...There is a cheap one on eBay (just search for 100W led heatsink) as well as a pricier one that uses heat pipes for $30. Keeping in mind each 90 degree bend in vapor-type cooling pipes reduces efficiency by like 30%.
From dealing with computers I would suggest buying a heatsink with a standard, replaceable fan since you're gluing the led permanently to the heatsink. The one you linked to will be a PITA to change out the fan.

Folks, I would be careful with regard to color temperature. I would be willing to bet that you could ask the guy for ANY color and he would be happy to provide "it" by simply choosing one of the 3 or 4 existing arrays and slapping a sticker on it for you.
Our concern for coral is the actual peaks in the spectral output, not the overall color rendering that they eye sees.
Have fun

Probably right :lolspin:
