Cofused on wiring strip build

So forgive my novice question, but... I am building an EB strip light, using 6 of the gen 2 strips. I purchased an HLG-240h-42b to pair with them. Based on the diagrams I see, I am to run the current side to a potentiometer to adjust. But everything I see show the voltage side hooked directly to the LED's... So my question is, how do I then adjust the voltage down to where it needs to be?

The voltage is set at 42v plus or minus the percentage established by MW. Current need to be controllable to lower current to the level you want. You have a Constant Voltage driver with variable current capabilities to max of watts/volts or 5 amps max. Watts = amps x volts 240w = x (48v) or x amps = 240w/48v.

Thank you for the prompt response. So basically, you are telling me the voltage will work itself out based on the current I am running. This helps a lot.

the voltage is established at 48v the spoecific range you purchased. You can lower the total amps to improve efficiency of your trips so that you do not drive the diodes over 200ma max current. Your strip has a maximum and minimum amperage per. Add the total number of strips and multiply by the say 88ma; 88mm x 6 = 528ma min, 1200ma max; so you an adjust down to a amp or less and get plenty of light.

So I show the voltage being about 39v on the 1120mm gen 2 strips... Am I missing something? Looks like the amperage for the driver is up to 5.72a, so that should give me a max of about 950 +/- ma each, correct? Just not sure where the 48v came in...
