We bought a nice LED lamp, Nemo Ellisse Pendant Double, which was said to be dimmable, but when receiving it there was a big IF !!! The lamp was not "standard" dimmable, instead it was dimmable with 1-10 VDC or 100 Kohm potentiometer.
The 1-10 VDC control is common in big installations, in public environment, since it can control a lot of lamps with one dimmer.
Checking the lamp I found that the AC/DC LED driver was a Mean Well LPF-90D and in the drivers specification the second IF was found !!
The lowest control level didn't switch of the lamp
