What about 4 cxb3590 (36v) with hlg185-1400 in middle, and 4 clu058 with 2 hlg185-1400 in my 4x4?
2-4-2 formation

Compared to the 3-4-3 configuration, I think this 2-4-2 might come out to be less expensive and more efficient. Am I correct?

You could bump those 058 up to 2100 and 240H driver, and two of them would be roughly equivalent to 4 3590s, as long as you can cool them.

this is the reason I selected the 185-1400 and not the 240-2100, just wondering if I would still have enough lumens to flower under.
are 140mm pc fans good enough to cool the clu058 on a 5.886" heatsink usa?
There is a million different configurations that you can choose from... at some point it's just down to personal preference/nitpicking. Any of these setups you mention will have sufficient light to grow dank buds dude. :peace:

With 8 cobs, personally, I think you should just build 2 bars.

And if you're just against that idea, use your 3-2-3. That'd be my next choice.

G'day all, thought I would share my latest build.
11 cxb 3590 running passive at 1400
Also there's 2 72v running at 1050 and another 3 running at 1400 from previous builds.
I've setup the cobs as follows.

---x-----x--- These 2 running st 1050
-x--x---x--x- Next 11 running on
--x---x---x-- 1 driver at
-x--x---x--x- 1400
--x---x---x-- These 3 of 1 driver running at 1400
The whole fixture is 1.2x1.2m.
Forgot about the baby's. Some white widow, purple haze and ak47

Why the extra framing?

"A nanocrystalline material that rapidly makes white light out of blue light has been developed by KAUST researchers (ACS Photonics)...
So-called visible-light communication (VLC) makes use of parts of the electromagnetic spectrum that are unregulated and is potentially more energy-efficient. VCL also offers a way to combine information transmission with illumination and display technologies—for example, using ceiling lights to provide internet connections to laptops.

Many such VLC applications require light-emitting diodes (LEDs) that produce white light. These are usually fabricated by combining a diode that emits blue light with phosphorous that turns some of this radiation into red and green light. However, this conversion process is not fast enough to match the speed at which the LED can be switched on and off.
“VLC using white light generated in this way is limited to about one hundred million bits per second,” said KAUST Professor of Electrical Engineering Boon Ooi.
Instead, Ooi, who is a member of the University's Photonics Laboratory, Associate Professor Osman Bakr from the KAUST Functional Nanomaterials Laboratory and their colleagues use a nanocrystal-based converter that enables much higher data rates.
The team created nanocrystals of cesium lead bromide that were roughly eight nanometers in size using a simple and cost-effective solution-based method that incorporated a conventional nitride phosphor. When illuminated by a blue laser light, the nanocrystals emitted green light while the nitride emitted red light. Together, these combined to create a warm white light."

neat! not exactly an LED, but still it seems lots of people like white light :)
