Which driver for a 72v cxb3590?

I got one cxb3590 @ 36v running with an HLG-60H-36A driver.
I also have another cxb3590 @ 72v, and no driver yet.

I'm debating between the HLG-60H-C700A & HLG-80H-C700A

I see they have 1 screw for adjusting power as opposed to 2 screw on my 36A (1 for wattage and 1 for voltage)
Is this 1 screw for adjusting wattage or voltage?

It adjusts current only
