Thanks Bobby
Go for a higher MA driver but a "B" version so you can dim. I don't know why anyone would buy anything but them for grow lights. That way you can crank it up as you flower.50W/sqft is way too much with 56% efficient cobs. you want like 30-35w
B version you add PwM or potentiometer too. A version doesn't "Dim" necessarily like the B does, It just turns it to 50% power. Not quite the same range like you get from a B with 10-100%.you can dim an A model too, just not remotely
Not only below, but above either, man. It's 50% or 100%. There's your choices.hadnt considered that, its called an 'Io' adjustment but yes they dont work below 50%
It's an internal pot with an adjustment range, not a switch. I actually own a few of the 'A' type drivers. The problem with them is keeping track of that infernal rubber plugThe ~ means One or The Other, man... notice how they're ALL 1/2's of the other? I know this for a fact. I did a lot of research on them.
the word is range not step!I did a lot of research on them.

So they CAN adjust in between 50-100%?It's an internal pot with an adjustment range, not a switch. I actually own a few of the 'A' type drivers. The problem with them is keeping track of that infernal rubber plug

18AWG can easily handle 3.6A which is maximum current for CXB3590. Holders are rated up to 4A. No need to worry.So, one concern I don't see being addressed here is wire. The 50-2303CR solderless connectors are limited to 18 gauge solid copper, which is only going to allow for about 5' of wire at these power levels. Less if you want higher driving currents/fewer chips.
You'll have to remove the solderless connectors from the cob holders(just clipped in) or use a different attachment method. Either way you're going to have to solder on the chips with this driver.
This driver combined with 16 CXB3590's would be a match made in heaven for a 4x4 space though. ~1100 umol/m² depending on the CCT.
I'm not so much worried about the current rating on the cob holder. Wouldn't the voltage drop from the 16.7 amp output of the meanwell HLG-600H-36 on 18AWG be cause for concern though?18AWG can easily handle 3.6A which is maximum current for CXB3590. Holders are rated up to 4A. No need to worry.
Your electrical experience is broad, it seems!no, because the cobs are wired in parallel. 16.7A would be split according to number of cobs

10@ 1.67A
20@ 0.835A
etc
the 16.7A is fed thru two pairs or 14GA conductors coming out of the driver. im gonna land each pair of them on one of these

and take off cobs from there. 18GA only sees current for individual cobs
easy breezy
