Yes, it will just run at full power then.

maybe a dumb question but how do i hook it up? i tried hooking a dimming wire to each side of the pot and it had no effect

One wire to the middle pin and one to either the left or right pin (this will determine clock or anti clockwise rotation of knob increasing or decreasing output)... sorry can't recall which does what...
Negative (black) to the outside...
Oh and add a resistor to the negative side of 10K so that it doesn't go below 10% output as recommended by Meanwell and increases the output of the Pot. at the top end as most only go to 90-96K with the 10K in series you should get the maximum 100K output.

ADD THE RESISTOR. Doesn't matter what size.go with 1/2 watt to keep it simple.also, if a 10k resistor isn't available, any number of other resistors that will Ultimately equal "10" or close to, will also work. (3-3.3's, 2-5's, 4-2.5's etc....)

Please heatshrink that resistor.

No. You're not supposed to.
heat, but in this case low voltage dimming circuit not an issue.

thanks fpr the quick replies, so 1/2w 10k resistor? i dont know much about this stuff...is there any chance i could have messed up the driver by connecting dimming leads to outside post on pot?

No you're fine. Just hook it up right with the resistor

ok cool thanks, i plan to run a 200w bar (4 72v 3590s at 700ma) and i want to run this in a 20"x36"x60" tent, i get a gram a watt in coco hempys with a premade apollo400w and apollo300w panel (pull around 280 at the plug), how would this light compare to my previous setup?
