Driving two CXB 3590 bars properly. 200W/300W

Reading here and there I found that for my 3 CXB 3590 @ 2.8ish 3500K bars, the best choice for a single driver would be HLG-320H-42, (does the 36 also works?). I need to buy them now and need to decide if the 36 will do or 42s are the way to go. According to the sheets, 42s...

But my doubt still is with my 200w bars... I want to use a single driver, running them @ 2.8ish 2 cobs.

Can you guys enlighten me?

cheers...

Bonjour
Do you want to run your cxb @2800mA each?
Or @1400mA?
I guess it is @1400mA to get the best of it!
Why don't you use the famous combo 4 cxb3590 3500ºk 36V CD on an hlg 185-1400b for 200w of 56% efficient cob!
I have great results with it so far!
And 350$ for 200w of the best cob available atm...it is nothing compared to the gpw you can pull from it!

The intention is to run them 36V @ 2.8

One bar 200W 2 cobs (missing single driver to push this), and a 300W bar (HLG-320H-36) 3 cobs.

I do like running in parallel, but not that close to the max. I would prefer to have a 2 cob buffer.
Say a wire comes lose on one, you won't have a total failure.

HLG-600H-42 would power all 5 @2.8a wouldn't it?

Bonjour
Is there a grow journal with 100w cxb3590?

HLG-240H-42 would drive up to 2.86A in parallel 36V COBs but as said before, if all current flows into one (for whatever reason) = toast.

The HLG-320H-42 will work for sure with 3 COBs in parallel. The -36 is only rated up to 36V for constant current and the CXB3590 is 37.25Vf @ 2.8A.

A SINGLE HLG-240H-42 Will drive two 36V CXB 3590s in parallel?
Is that correct?

Yes. Well, you can run a whole bunch in parallel but the current is decreased to each COB. Ten COBs in parallel would receive 0.572A each.
