When the off button of a nPODM D is pressed, the dimming wires will go to approximately 0.6 VDC.
The effect upon the light level depends entirely upon the dimming driver in the light fixture.
Some drivers will go into sleep mode (off) below 1.0 VDC. In this case the lights will appear to go off.
Other drivers will accept the 0.6 VDC as a working dim level and the lights will maintain a dim level.
