Smoothness of Dimming

There were a few areas of criticism for this fitting with all the dimmers. There was no static flicker observed at any output level. However there was a noticeable shimmer during fading with all of the dimmers tested. There was also a step up at minimum level in the profile of all the dimmers. The RML-500 was also inconsistent when turning on.

Audible Noise

There was a Buzz on the RML-500
