Smoothness of Dimming

There were a few areas of criticism for this fitting with all the dimmers tested. There was no static flicker observed at any output level. However there was a slight shimmer while fading on the RMT-500 and RAK4-T but this was worse on the RML-500. The profile of the RMT-500 and WMT-400 were both grouped towards the top where as the profile of the RML-500 was grouped towards the bottom. There was a slight inconsistency with the RML-500 when at a certain level they all turned on one after another instead of at the same time.

Audible Noise

There was a buzz when testing with the RML-500 this was worse at low level but stopped at 100%.
