Dimming Performance

RMT Minimum brightness from off: 1% Minimum brightness from max: 1% RML Minimum brightness from off: 5% Minimum brightness from max: 5% RAK Minimum brightness from off: 2% Minimum brightness from max: 2%

Smoothness of Dimming

With all dimmer types this lamp performed well. Static flicker was observed but only when the dimmer was at the very minimum output, this is unlikely to be visible during normal operation. Some shimmer was present when fading between levels. The profile in general was smooth, with no visible steps, and related dimmer to light output fairly linearly.

Audible Noise

No audible noise when tested with any dimmer.


Extremely noisy unfiltered signal. Possibility of interference with nearby electronics (paticularly radios)
