Smoothness of Dimming

This driver had a few issues with all the dimmers it was tested with. There was a slight static flicker at the bottom end with the RAK4-T and WMT-400. There was also a slight shimmer when dimming with the RML-500 and RAK4-T. The profile of the RML-500 and WMT-400 were both good but the profile of the WMT-400 was slightly grouped towards the top.

Audible Noise

There was a loud buzz when testing with the RML-500. There was a quieter buzz when testing with the WMT-400 when at a low level.
