Why are folks always recommending the B version drivers?
I got a A version 240W 1750mA with the internal pot and I think it's totally fine.
Why do you go through the hassles with connecting pots etc. if there's already one there? For the wider dimming range? (The one I have with the internal pot goes from 850mA to 1750mA by the way, totally fine for me)
There are a few reason, many to most of them, just personal choice.
-Wider dimming range,
-Connect multiple drivers to one knob
-Cool knob options(aluminum, anodized, gold...)
-Use of PWM and automated controllers(sunrise/sunset programs, high heat power down)
-Not have to get on top of the driver and use a little screwdriver like the A...external of the room even/ease of access.
-Cause that's what people they are following used
If someone considers installing a pot a hassle...than it's clearly not for them. It should not be a deterrent, if they installed the driver, they can do the pot in 10 seconds. It's just a choice.
