Can't say without measuring the pot on that driver. You "might" be able to squeak out another 10W-15W.

Would I be able to measure it with a multimeter? Like the Ohms setting I'm guessing, if I hook it up to it? And if it reads 85k, I would want a 15k resistor, correct, or am I confused?

Yup, measure ohms on the two outside connectors.

Thanks for clearing this stuff up for me.

So the resistor isn't there to protect the board or driver? Sorry, but this stuff isn't starting to click, lol.

It's a resistor feedback circuit. The driver outputs a signal through the resistor and/or potentiometer and makes adjustments based on how the signal is altered by resistance.

So the more resistance it reads the higher it will want to go up to a point where it maxes out? Sorry if I sound like a dumbass, lol.

Sorry to cut in, but I was trying to follow along. This is right along the lines of my thread lol. I just got 3 qb288 rspec boards and a hlg-480h-54b driver. Can I find a cased potentiometer with resistor built in? If not what potentiometer and resistor should I use?

That's it. Anything from 100K to OL/infinite resistance is driven at 100%

Thanks. It's starting to make sense finally, lol.

I have MUCH more studying to do after the holidays. I got a decent SOG goin with 3 gals under my amazon special. I'd like to build a better set up before I switch, took cuts tonight Soni have some time....
Honestly over half the info here is Greek to me right now!
Appreciate the wealth of knowledge though, thanks yall
