    Which is best?

    I will be running potentiometers for the foreseeable but may consider a controller in the future...

    Thanks in advance for any advice.

    I believe the D dims from 10% to 100%, but not down to 0. Not sure about the P.

    I would think the D would be easier to dim 0-10V using a pot.

    You would need something like an Arduino to provide a PWM signal for the P though. These aren't that expensive though ~15. But I'm pretty sure the P will dim down to 0. Best check this bit first.

    I think the p driver suffers from the 10% dimming issue too - as far as I know anyway. Would be worth checking before purchase though - I'm sure someone on here can confirm it either way.

    If you look at the spec sheet
    http://www.meanwelldirect.co.uk/publ...%5Cr1444_3.pdf

    You'll see the D goes down to about 5% and the P to 15%

    If you may go with a controller in future it would be a good ideal to decide on which you would use before selecting a driver as they require different controllers, one needing a PWM signal ant the other 0-10v.

    Some of the Recom drivers will run from either type of controller but they tend to be more expensive.

    From what I've read the P doesn't dim as smoothly with a pot but the D can't use a controller? Essentially suggesting the P is more flexible?

    The P doesn't dim with a pot, it needs a PWM signal. Or it can be run at its max set current by supplying a constant 10v to the dim wire.

    I say set current as both the P and D version have an internal pot, accessed by removing the top cover, which can be used to set the current.

    The D can be used with the correct controller.
