New tank and LED lighting

[Fishy!]

Hey! I have been out of the hobby for a number of years now. Getting back into it I can see a lot has changed!

The tank:
15 gal column tank
13w x 13d x 20t

I have added the substrate and 12lbs of live rock. I plan to add approx 10 more lbs to get closer to the top and to fill it out a bit aesthetically.

I have been doing some research into led lighting. I have come up with this: http://www.jlaquatics.com/product/ld...850+50%29.html
as my best option for this tank, both size and cost wise. I want to run 3 of these strips, color configuration yet to be decided. This will be in addition to the 12" T-5 single bulb(9w?) already in the hood. What do you guys think? I would have to guess this will be lots of light for any corals I may put in? I know it's a deep tank for its size but it's not a 90 gal deep. Any input would be greatly appreciated as I have 0 experience with led tank lighting.
