Smoothness of Dimming

There were a number of areas of criticism for this lamp. There was some flickering at the minimum level on the RMT-500 and WMT-400. While testing with an RMT-500 and RAK4-T there was shimmering while fading. There was a step up in the profile of the RAK4-T when at the minimum level. When at the maximum level the WMT-400 started to flash.

Audible Noise

No audible noise when tested with any recommended dimmer.


When tested with RML-500 doesn't turn off and flickers at minimum level. With the WMT-400 the fitting flashed at the maximum level. For these reasons neither dimmer can be recommended for use with this fitting.
