DIY LED build help!

Hey everyone
I have been using diy chinese epileds for sometime and after they keep dying on me. I finally ordered me some cree leds. Now I will be getting some 5 x XML-L2s Cool white, 30 x XTE 4500K, 20 x XTE 10000K, 10 x XPE blue and 20 x 3W 660nm red LEDs. My main tank is 18"H x 48"L x 15"W. The other 3 tanks are of 39"L x 15"H x 15"W. Now the problem is my 4 heatsinks are around 18"L x 2.5"W x 3" tall. 2 are 6"W x 6"L x 10"H. I wont be using any lens as drilling is too much work and gluing lens has resulted in hours wasted if a led fails in a series string.

I am aiming for high/very high light as I have some demanding as hell plants. What should be the ratio mixing of on each panel, what wattage should I aim for (I plan to run lots of fans on leds as they will cool my tank too), how many leds on each panel and what distance should I aim for from substrate level to grow a nice thick forground of HC cuba.

There is no such thing as an XT-E that has a color temperature of 10,000K. They don't bin them that high. I would question your source about the legitimacy of these LEDs.

I would skip the reds and the neutral white (which give a LOT of green, too much so for a planted tank). Use a 1:1 or a 2:1 mixture of cool white to warm white, if you can get Rebel ES lime then add a few of those, and then blue and a bit of cyan.

Another option instead of dozens of piddly little LEDs would be Bridgelux Vero arrays. They are inexpensive, though if your location is correct, getting them can be complicated, but if you are already ordering them from the US, then they are an option. They provide incredible color and incredible output, demolishing the XT-E and XM-L2.
