Help with dimming multiple drivers

Hello friends.
I cant seem to find a definitive answer to my question so I hope you guys can help.
how can I dim smoothly 6 HLG-240h-48b drivers with one device such as a dimmer or maybe something smarter but cheap? will a 16.5k ohm potentiometer work??

Also.. I'm planing a build with the lm301b qb288 3000k board with the 2 rows of epistar 660nm from alibaba ... any input on these boards will be highly appreciated!

Thank you!

That is correct. Each set of DIM leads carries a 0.1mA constant current that flows thru your dimming potentiometer, so six dim leads wired in parallel will have 0.1mA x 6 = 0.6mA.

0.0006 Amps x 16500 Ohms = 9.9 Volts. Put a switch in between the dimming pot and the dimming wires. Open the switch to achieve at full power at 10 Volts.

No opinion on Alibaba gear. I prefer support vendors that have feet on my soil.
