Dimming Performance

Minimum brightness from off: 3% Minimum brightness from max: 2%

Smoothness of Dimming

In general this lamp and driver performed well and broadly consistently across all dimmers. There was no static flicker at any output level with any dimmer and the profile was smooth and continuous across the board. A slight shimmer while fading between levels was observed with all dimmers except the WMT-400. This shimmer was more noticeable with the RML500 than with either of the other trailing edge dimmers (RMT-500/RAK4-T).

Audible Noise

No audible noise when tested with any recommended dimmer.
