_NOT_ a grower, CREE CXB3950 with Meanwell HLG 185H - C700B?

I bought two 72v CXB3590 and a Meanwell HLG 185H - C700B, will there be anything extra in the circuit to illuminate 2 of these LEDs?

Sorry, I"m not a grower and everyone keeps pointing me to people who are for help. Ultimately, I plan on using at least 2 of these LEDs to bounce light in an amphitheater to create a shadow of a Batman sign. I read the spec sheet on both and while I understand (I think) the LED spec sheet, the power supply sheet throws me off. Clearly I'm not seasoned in reading spec sheets to begin with, but the power supply mentions variable output voltage, which instinctively leads me to thinking about things like resistors, buck converters and adding other components to the circuit.

Any help is appreciated.

Ya, the need for another COB, possibly 2.
What's the Min-Max voltage range on that driver again?
200watt driver, only using 100 of them.
72Vx700mA=50.4watts.

Ya you're literally just BARELY brushing the threshold of enough voltage for the driver to even run. It will run 4 of those 72V COBs damn near perfectly. 72x4=288. Even though it's 286, it will still be fine. They have a little wiggle room.

So, I just plug it in and short the connections with regular wire, no other components in the circuit? It's that easy?

You run them in series. Positive from driver goes to first positive of cob, then a wire connection between that 1st cob negative to the next cobs positive Continued until the 4th cobs negative which returns to the drivers negative wire lead. That's it.
