Dimming Performance

RMT-500/WMT-400: Minimum brightness from off: <1% Minimum brightness from max: <1% RAK4-T/RML-500: Minimum brightness from off: 10% Minimum brightness from max: 10%

Smoothness of Dimming

This lamp performed well with all dimmers, but noticeable better with the WMT. No flicker was visible at any output level although when tested when the RMT-500/RML-500/RAK4-T a shimmer while fading between levels was observed. The profile with most dimmers was smooth and continuous although a sudden step when turning on could be seen with the RML-500.

Audible Noise

No audible noise when tested with any recommended dimmer.


A rating of "good" is the maximum available for the RAK4-T and RML-500 due to the minimum brightness tested being around 10% of maximum the output. Also with leading edge dimmers due to the very noisy waveform there is the potential of EMC issues.
