    Question Grafik Eye 3000 and Modern Forms Chandelier

    Hi - just bought a house that is outfitted with 4 Grafik Eye 3000 systems. I replaced an existing incandescent chandelier with an LED model from Modern Forms. The light dims beautifully, but the built-in transformer buzzes. Speaking with Modern Forms, they just say to use an ELV dimmer.Is there a solution to stop the buzzing or am I returning the chandelier?Thanks!

    The GRX-3000s only do forward phase dimming. ELV loads require reverse phase dimming. You can add an interface like the PHPM-PA-120 that supports reverse phase dimming.
