    Caseta compatible 2x4 dimmable LED panel light

    I want to replace two 2'x4' CFL troffer lights with an equivalent 2'x4' dimmable LED panel light. I stopped by my local hardware store and picked up two Lithonia CPX 2x4 4000LM M2 panels only to find out that they are not residential grade and not compatible with Caseta dimmers. They turn on, with a flash, and stay lit fine, dimming causes flashing of the panels. The Caseta switch I have is a P-PKG1W-WH-R, open to getting a different one if needed. I asked the hardware store if they had any recommendations on panel lights and they didn't, said to reach out to Lithonia and Lutron. Emailed Lithonia and they weren't sure if any of their lights were compatible. Lutron didn't provide any options either. Has anyone had any success with dimmable LED panel lights?

    It looks like those Lithonia lights are 0-10v dimmable. To dim 0-10v lights in Caseta, you will need to look at using something like the PD-10NXD (neutral needs to be connected for this application) and a GRX-TVI dimming interface. The GRX-TVI will be wired between the dimmer and the lights (it will also have a constant hot connection). The GRX-TVI will essentially translate a normal phase cut dimming signal from the PD-10NXD and translate that into the low voltage 0-10v signal your fixture requires. Please see below for links to both the PD-10NXD and the GRX-TVI.
