Check the listing for details. Osram Phase Cut dimming module EN-PCDM-GB2 Encelium. Condition: Open box. Listed at 79.00 USD. This listing is for ONE, Osram Phase Cut dimming module EN-PCDM-GB2. Part of Osram Encelium lighting controls system. These were installed in a new building and never energized. Because Encelium was not able to provide the building master controller or even a production date, we had to uninstall all of the Encelium components and replace with nLight Air. I am listing these as new open box but the argument could be made that they are used due to being installed, but never energized, consider this accordingly. We did not get power to the building until after we had installed the Acuity system in July 2023.These will not be shipped in the original box.
