Smoothness of Dimming

This lamp performed fairly well with all dimmers although best with trailing edge dimmers. There was no static flicker observed at any output level. There was a step up at the minimum level with all dimmers tested. There was also a flash at the top end when used with the RMT-500 and WMT-400. There were steps in the profiles of all the dimmers. During the mid range the RML-500,RAK4-T and WMT-400 shimmered when fading.

Audible Noise

There was a slight buzz heard on the RML-500.


"Maximum number of fittings" will be to a degree dependent on the variety of fittings used. The stated values are a conservative estimate.
