Dimming Performance

RMT Minimum brightness from off: 2% RMT: Minimum brightness from max: 2% RML: Minimum brightness from off: 5% RML: Minimum brightness from max: 5% RAK4-T: Minimum brightness from off: 20% RAK4-T: Minimum brightness from max: 20%

Smoothness of Dimming

In terms of the smoothness of dimming this lamp and driver combination performed well. When tested with the RMT no flicker or strobe was observed as was a continuous dimming profile with no visible steps. When tested with both the RML and the RAK4-T the same result was the same except for a visible flicker at the very bottom of the output range,

Audible Noise

Noticable buzz when used with leading edge dimmer. No audible noise when used with trailing edge dimmer.


The extreme variation in minimum light output values stated is due to a variation in the power-supply used in stand alone modules and RAK modules. Editing the profile via Rasoft can improve this issue but the results stated here are for a RAK4-T on default settings.
