I didn't think that I would need to dim lower than 150W, so I chose the driver version featuring an internal potentiometer that can be adjusted from the outside, in hindsight I should have chosen the one which featured a input to which one may connect a 0V - 10V signal, a PWM or a potentiometer to dim the LED's.
The maximum output voltage isn't much more than what the LED's demand, I was actually concerned it might be a little to low but it worked fine.
I will contact Mean Well to ask them about this.
Thanks for your advice.
