with a 4x4 tent would it be worth running 16 cobs or would 12 be best?, would the extra 4 be worth it price wise and the extra watts or would it not really be as efficient for yields? i know more cobs i can dim but if they were all at full power would the be much of a difference?
The ability to dim is useful when your unsure, the extra cost of 4 is a little salty upfront but you give your self a better light range possibility(PPFD) but others here may have a better idea

Hi mark, are the 400w drivers only available in 1400ma ?

First off, HUGE thanks to you for getting this together! Ive been following on YouTube for a couple months now and I really dig the stuff you're doing and the fact that you take time to film/edit/narrate for the rest of us. Awesome.

And since you asked.....what's your input on these three layouts? Is keeping in a staight line best? Staggered? Last option is with a little less coverage in one corner,which I'm not a fan of,but I may have an intake duct hanging down in that corner anyway (undecided on setup, only round 2 for me). Space is ~4x2.

Thanks in advanced for your input.

I'd go with the second option.

I would go with four cobs spread out and the fifth in the middle of the four. peace

Odds are, you're right....this did seem a bit simpler to construct though, so figured I'd test it out. All input appreciated, so gracias!
-if you take the extra time and angled aluminum to build a frame that has 2 or 3 parallel rails for holding these 107mm wide heatsinks, you can initially leave them loose. just pressed between the angled aluminum (no screws)

-leave some slack in the wires between each cob so that you can slide them and move them.
-then using a $30 lumen meter from amazon, you can micro adjust the spacing of each heatsink for optimal spread.

-alternatively. you could drill a series of holes in this rail system and just use one heatsink mounting screw per side of each heatsink. and you can inch them up and down the rails to get it perfect.
-a lumen meter will give you relative intensity to get your perfect spacing without the expense of a PAR meter.
