Ok so you might be right. But what would I do now ?

What is pwm ?

I have the 320w model it doesn’t dim all the way off with the knob it came with. On the ballast it says model B but then there’s a label slapped on that says AB.

I’ll have to check tomorrow. Are you talking about the last screen where you put light % and time ? I’m trying to hook up 4-5 lights with the ECS 2 adapter connected to the LMA 14.

LMA 14 adapter and I already set it to LED

Does anyone know if the AB model meanwell driver works with the Hydro X ? I have the correct adapters but it’s not dimming to proper % and also won’t turn off on the timer
