OK, so if I want to dim 4 drivers together and be able to achieve max output, could a 10k pot be used? I'm going to have 4 drivers running the 5000k and the other 4 drivers running the 2700k, if at all possible and feasible I'd like to be able to dim them all at once, for simplicity and uniformity.

yes, but it could to be hard to dial in anything between 0-100% because of the logarithmic response curve of the driver's dimming leads to resistance applied.
i guess the more drivers you connect to one potentiometer the harder it will get

Would a lower one work better then, maybe 5k?

5k might really work a bit better if you look at the curve i posted on page 1.
BUT u probably wouldn't reach full 100% output

5k only reaches about 70% of max on these drivers.

10k ohm, but the more drivers you add the harder it is to dial it in.
