Pre-planning for upgrading the 8'er, some input on LEDs needed

[The Grizz]

So I am planning a fairly small upgrade to my 165 gal 8'er...................and YES, I can hear some of you saying..........WTF! Here he goes again!!

But when a good deal comes my way............I just can't pass it up

I have made the decision to get the glass cut for a 8' x 2' x 2' INSIDE DIMENSIONS.........roughly a little shy of 240 gals.

Not sure on the sump yet but it will be a much better design then my 165. After my wife seen pics of Mike' 8'er in Manitoba she wants me to build a complete wall unit that will be 12' long x 8' tall. I have a skimmer I really like, 2 MR1 reactors for Vertex Bio Pellets & Carbon, Profilux 2ex controller, probes, power bars & doser & more then enough pumps to provide mass flow but................

My biggest decision is going to be lighting........I would like to go with LED's but don't know much about them. How many LED's would I need? Do I DIY or buy fixtures? Any ideas would be greatly appreciated.
