Smoothness of Dimming

This fitting performed well with all the dimmers it was tested with but there were a few areas of criticism. There was no static flicker at any output level with this fitting. There was some noticeable shimmer when fading with the RML-500 and WMT-400. The profile of both the RML-500 and WMT-400 was grouped at the top end.

Audible Noise

There was a slight buzz when tested with the RML-500.
