LED light design

I am designing an LED light for my 40 gallon cube and I am trying to keep it under $200.
Design plans and assumptions: - LEDs will be placed on the tank glass, which is at the water surface - Corals are softies, but I may add some LPS (I like things that move.) - Tank dimensions are 24x24x19 (length x width x depth)
I open to opinions.
Thank you, Bob.

Are you using the 1" U channel with or without a fan? My firewall will not accept www.aquastyleonline.com. I thought the red leds were good to accent the coral color.

 

The link to the 20 watt multichips did not work. I want to drive the whites and blues at 1.3A and the UV can only handle 350mA, so I was planning to drive the UVs with the moonlight driver. From my reading most people seem to like either 60% blue to 40% white or 1:1. I have not read many using the UVs, but since the wavelength is above 400 and below the royal blue it seems like they would be good for photosynthesis.

 

How do people feel about the Bridgelux LEDs vs the Cree? I am partial to the Cree and have heard good things about them, but the Bridgelux are much cheaper. This deal from http://www.aquastyleonline.com/products/Aquarium-24--LEDs--DIY-Dimmable-Kit.html is really good at $99.
