Will this Potentiometer work?

Found it at radio shack and wanted to make sure it was the right one before a friend hooks it up

10K-OHM
500VDC- .5W

Got 8 3590's running under a 185-700
Upgrading to 185-1400 and its understood that these will run hot and it would be in the best interest to dim these down a bit instead of running them at 100%
So would this pot work?

If you're running 2 185-1400s and wiring the dim wires together you will need a 50K ohm potentiometer. As long as your cooling solution is adequate they won't run hot, but it might be nice to be able to dim them.

It would never be able to go higher than 10% brightness. However, if you wired 10 together you'd have a very precise dimmer. You'd have to turn 10 knobs though.

Which points get connected any two?

Thanks for the help found a 50k and came across 2 100k for future use

On the potentiometer, the middle connects to the wiper (dial). The right or left are connected to the ends of the resistance material. The dial should turn normally when the middle and left contacts are used, in reverse when the middle and right contacts are used.

How about 5 cobs running on a Pairui LGSU-1400D driver?

Which one do I need please?

With output voltage of 52-86 you could only run 2 36v COBs or one 72v. For 5x36v you need a driver that puts out around 180v. Might as well just go to 6 COBs on a HLG-240H (238v), or find something that puts out 180v. I don't know which one that is offhand.

BobCajun which would be the best HLG 240 to run 6 cobs on? This stuff boggles the mind so many possibilities

I go big on everything and rely on my breakers to snap if I run into a smoked Light Circuit.There are so many parts lying around everywhere, Welding Machines,Sound Equipment and in the event I can't find the part then I build it.I'm like Tony Stark on a low budget.

The driver is part of the cutter mau5 grow kit and I added an extra cob per specs. It's a 250 watt driver so it should be able to run that. Knowing myself I'm sure I'll replace the driver later and go bigger but I need to set it up as is with 4 cob kit plus 1

Oh, I didn't know that was in the kit. I was just going by a data sheet. Guess it must work then.
