Citi-1212 DIY Build

What do you guys think about a 4 ft light rail holding 8 citizen clu048-1212 cobs (4@2700k and 4@3000k)? Its gna be running off the HVGC320-1050A. Or would it be optimal to space them out more and have 6 on the rail and individually mount the other 2 for the undercanopy or something? Heres what i mocked up. Input would be awesome, @CobKits, @Growmau5, @SupraSPL, @coreywebster and anybody n everybody inbetween.

Linear doesn't work that well ... Too much light down the middle because the cobs are too close together....
You want an even spread with cobs spaced 12" apart on all sides.. I just rebuilt my frame in May...
This was my design.. . You could run 4 cross pieces.. killer coverage!!

True but when considering i already have 2) 4 ft rails with 4 1818s on each in the 5 ft X 7 ft room, coverage is there as far as spread. Those 2 lights are spread over a canopy 5ft L X 3ft W (2 plants). Im looking to maximize light density/coverage as much as possible to push my canopy to the full size of the room, with 3 rails, to fit 4 plants total. 2 rails of the previous description plus the rail pictured in the op.

Heres what i have so far....like previously stated, room is a total of 5ft W X 7ft L. Im trying to maximize light coverage with the 2 rails already in place, with the addition of a 3rd rail, either 8 cobs on one rail or 6 with 2 designated for the under canopy. The driver will run 8 so i bought 8. I need some advice as far as 6 or 8 on the rail...

I guess its worth mentioning im using rectangle aluminum tubing. Not the angle aluminum most people use. Its sturdier and more ridgid than the economical angle choice. Plus less to assemble. All you need is to drill out heatsink holes and drop em in. Easy peasy. Much more in price but better aesthetic appeal.

Well. I went with 8. If its too much when i light her up, i do have a spare tube. Figured if i wanted to add another one later on down the road, why pay double shipping. And i got it cheaper buying it 8 ft section n cutting it myself in half. So if it is too bright down the middle then i throw on maybe 5 or 6 on this extra tube and mount the leftover 2 or 3 cobs either up top somewhere inbetween the rails or on the under canopy. To bud up them bottoms a bit more. Either way, shits going to be insanely bright. Ill have the 1818s on the sides, the 1212s in the middle to start. Possibility of pushing this light into veg room and dimming it all the way down and putting the current veg light (same as flower rails but 4000k only) into the flower room and keep the flower room all 1818s evenly spaced. Pulling 6-9 oz per plant (2 month veg) right now off just the 1818s, cant wait to play with these rails and see what i can make happen.

I've ran 3 cxb 3070's at double that amperage, 2100, and they get pretty frickin hot. This is on heatsinkusa 5.8" profile. Best of luck. If you got fans actively cooling, you'll be fine.

Im using iceled ultra. Theyre active cooling up to 200w. Beasts.

Its not the final layout, just a quick snapshot after i got her hung up n wired. The 8 cob rail will be center, with the 4 cob rails on the outsides. Bitches are bright as hell. Easily could fit another 2 plants this size. Fwiw, the canopy of each of these plants is 3 ft deep, 3.5 ft long, and about 2-2.5 ft tall. Short n fat.
