Ah, I just worked it out with my dimensions and it's 1.6ft2 (micro grow), put meters by accident

I'd wire those strips in series and drive them with an HLG-60H-C700A. This saves a few bucks by not needing to buy the Wago Lever-Lock connectors used for parallel panel builds. This will drive up to nine 340mm EB3 slim strips. The driver will crank out 98.1 Volts DC to light nine strips ( 76.3 VDC with seven strips) with 0.70 Amps. The driver's max output voltage is 100 VDC.

The dimmer pot controls both current on constant current drivers and voltage on constant voltage drivers. Power (watts) = Volts x Current. So the dimmer pot also controls watts, because Watts is directly proportional to voltage across the LEDs and current flowing thru the LEDs.
If you go with seven 320mm strips, you could use one far red strip to boost your spectrum.

I will take this advice and go with your recommendation, thank you so much for your help, honestly appreciate it so much,
I definitely had misunderstandings with regards to voltage, didn't realise voltage could be split between the strips. I will connect in series, seems a lot simpler too,
Do you know is the pot tells me the current/voltage currently being set? Or do I need multimeter to see exactly how much voltage/current I am passing through the LEDs? I am worried about light burn by powering them too high of current or too high of voltage.

I mounted my dimmer pot with a paper disk behind the pot's knob. Plugged the driver into an kill-a-watt meter to calibrate the paper disk. Starting with the pot counter-clockwise, read the kill-a-watt, and recorded the kill-a-watt readings onto the paper disk, turn it clockwise and record the knob settings at different power levels.
Have fun and enjoy the fruits of your labor.
EDIT. The A version of the meanwell driver does not use an external dimmer potentiometer, the pots are built in. The B versions use an external pot dimmer.

just finished my new light.
56 bridgelux EB3 slim 340mm 3000k 80cri on a t.slot frame, no heatsink.
Maxed out a HLG320 2100mA (14S 4P), 525mA each strip, roughly 5-6W.
went with a slight logarithmic arrangement, spread is very nice n even.
Output is insane.

What the actual power for this lamp and it also installed Meanwell driver there , looks like 2 n 1 on the board , can they be parted in two ? the QB light to be most growers's choose now, i have the TS-1000W marsled it's little small but it performance well in my room. love qb tech .

the power draw is 320 watts at the wall, using a meanwell hlg320.
You can mount the strips however you want, can be parted etc., for me these fit well, wanted a square.
with no airflow at all at 86F ambient i get arround 110F on the strips.
This will improve in a real world setup a lot, with fans on etc.

It's cool in such design, the board can be parted and combined, i do like it and would considered try out this one, while due to the price point i went with the ts2000 one few months earlier,, it a square one but cannnot parted,for me it's fine. i love try new led tech, next i may check out the hlg one.

Any expectation on how close your going to be able to run that?
Looks awesome.

thanks.
I plan to use it at roughly 12", but it is not in the tent it will be in the end.
Think 12" is absolute max for me at full power, easily get above 60k lux there, more then 800ppf.
Even with CO2 i could fullfill all demands in a 3x3.

pretty impressed by the eb3 slim strips so far.
made some rough comparsions with a lux meter to a similar sized similar wattage 6 boards lm301b setup.
the strip light wins, better spread and more lumen.
one reason is of course also the better utilisation of the driver with the eb3 setup, but still, these chips do well.
btw, the slims are all in stock again.

what you see is a 80x80cm, but it will be in a 3x3 in the end, should work nice.
Hey guys, so I finished building my 7 strips Eb3 wired in series with HLG-60H-C700A, but my lights flash on and off, consistently 1 flash per second, even when I turn the dimmer screw up to max they maintain the constant flash, I removed one of the strips, from 7 to 6, and the same thing happens, they're all flashing so I'm guessing my connections are fine?

That sounds like too much voltage for the driver, whats the voltage calculations look like for your build? Looking at the blux datasheet tht driver will only power 4, possibly 5 strips, depending on the size. Are they 1,2 or 4 feet?
Ah okay,
It's the 1 foot strips, here's a quote of the advice I took from earlier in the forum, as I really wasn't sure about which driver I would need:
"I'd wire those strips in series and drive them with an HLG-60H-C700A. This saves a few bucks by not needing to buy the Wago Lever-Lock connectors used for parallel panel builds. This will drive up to nine 340mm EB3 slim strips. The driver will crank out 98.1 Volts DC to light nine strips ( 76.3 VDC with seven strips) with 0.70 Amps. The driver's max output voltage is 100 VDC."
I thought I could drive 9 strips with the driver? And since I only have 7 it would be fine?
