DIY design and help

Hey guys I am trying to come up with a plan for a DIY led that can cover 4x8 and I am liking the looks of one of Growmou5 designs. I would like to follow the idea he came up with that I uploaded, but add an extra 4 cob bar in to it. I would also like to use CXA3070 instead because I am in Canada and the CXB3590 are just under 100 bucks here.

Now I have a few questions still. Would me using the 3070 make w huge difference? I haven't really found out what the main difference between 3070 and 3590 really is.

What lumens would you guys suggest? I was thinking 3500k, but I've seen 3000k, 3500k, and 4000k.

Lastly what drivers would work the best? I'm not sure what the formula is to figuring out the watts and par. The drivers in the picture are roughly 110 Canadian, so I was hoping there would be something a little cheaper that would do the something.

Thanks.

I would strongly suggest reading most of @SupraSPLs Threads. Also give the calc a try and that should give you some good info for your 3070 vs 3590 comparison for your set up

I honestly don't really understand it at all. I know what i want to design, and how much I want to pay. The difference betweem CXA vs CXB and 3070 vs 3590, as well as amps volts and what driver to select is over my head. I've been reading for two weeks now, an I just don't get it.
