Smoothness of Dimming

There were a few areas of criticism for this fitting when tested with trailing edge dimmers. There was no static flicker observed at any output level. However there was a slight flicker while fading with all the dimmers. The profiles of the RMT-500 and WMT-400 were both grouped towards the top whereas the RAK4-Ts profile had steps up.

Audible Noise

No audible noise when tested with any of the dimmers.
