Smoothness of Dimming
There were a few areas of criticism for this fitting with trailing edge dimmers. There was a static flicker observed on the RMT-500 when at a low level. There was also a shimmer while fading observed when tested with the RMT-500 and RAK4-T. When tested with the RAK4-T there was a step up in the profile whereas with the WMT-400 it was grouped towards the top end.
No audible noise when tested with any of the dimmers.
