Smoothness of Dimming

This lamp had several noticeable areas of criticism. The fitting and diver combination flickered at the minimum level and there was a significant shimmer as the lamps faded between levels. The profile was reasonably smooth and continuous.

Audible Noise

No audible noise when tested with any dimmer.


One of the three drivers failed during testing causing the fitting to flash violently.
