So here are some final shots as the master fixture came together. The slave is the same except orientation reversed and minus the ATI Controller.

So once fully assembled and running both fixture in concert, it looks something like this. The first shows them running with the slave's reflectors off followed by them being installed.

So there you have it. If you've been considering doing something like this, hopefully it gave you some ideas and even considerations for possibly ways to better suit your needs. After running all T5 and LED at 100% for about an hour, the internal temperature is right at 37C.
sahin - Excellent job. I carried out something along these lines many years ago before ATI released their hybrid lights. I know too well how dealing with the heat is an issue but I can see you've thought about that.
A lot of air needs to be pulled into the unit to keep the heatsinks for the LED's cool, but also to keep the internal temperature low enough so that the air that passes over the T5 tubes isnt too hot; otherwise you lose the active cooling effect over the T5's and they will degrade faster than they should on an ATI unit.
I also own an ATI LED Powermodule and I can tell you that the shimmer effect is pretty good on the LED Powermodule despite having 8 T5 tubes.
All in all an excellent job and I look forward to knowing how it all works out. I'd put it all together and run it for some hours to see if the heat is managed well. It from what I see, all appears well thought out.
An excellent job indeed.

Take a gander at the photo here. The BlueFish uses simple 1/8" Stereo M/M cables for its signaling. What I did to make things serviceable and easier for my purposes, was to cut these stereo cables and run them to a terminal block (The little green blocks in the photo). From here there they are run to each channel of the Rapid LED LDD 4-Up boards. This photo only shows 2 of the 4-Up boards, which is one half of the overall dual 48" fixture. You have to "splice" the lines (parallel) so that each channel receives the same signal for that channel. In other words, Channel #1 out of the BlueFish is "split or spliced" to the Blue channel of All the 4-Up LDD boards. Then Channel #2 is done the same way to the Color channel and so on.
IMPORTANT - The Mini BlueFish can only be split off of each channel to 3 LDD (3.4V limitation). I needed it to split 4 ways, so I had to go with the full BlueFish controller, otherwise the Mini would have done it for me. The Full version can provide 5V PWM signals.
As far as the final two Channels of the BlueFish, I use one to control my Moonlights and the other my LED fans.
Hope this helps, if not, ask again and I'll try to clear up the fuzzy.
Corey,
Not sure yet. My wife and I are planning to hang the fixtures this coming Saturday morning before the tank's sunrise. I'm going to take PAR readings with the MH/T5 running tomorrow so I can hopefully gauge where we are currently and where I need to be with the LED/T5. We've had absolutely incredible growth and coloring since going back to MH this past November. I'm actually really worried. Hopefully the change will be positive or at least on PAR, otherwise I'll be looking forward to the winter months when the MH/T5 go back up.
AZRippster, just out of curiousity... what are the dimensions of your tank?
Yeah I understand. I just spoke to Dave @ Hamilton technology about maybe going back to halide but adding T5 this time. Then I can shorten the halide time to help with the heat. I'm in Ohio, not as hot but it gets humid. Plus I'm in a small apartment so it holds heat.

I'm probably at least 3 months out from my new tank. I'll be interested to know how the growth does in comparison to the halides
