Dimming Performance

Minimum brightness from off: 1% Minimum brightness from max: 1%

Smoothness of Dimming

With both leading and trailing edge dimmers this lamp and driver combination shimmered while fading between levels. With the trailing edge dimmers this was only noticeable in the bottom half of the output range but with leading edge it was visible when fading between any level. With the leading edge dimmer there was also some flickering of the lamp when dimmed below around 3%. With both leading and trailing edge the dimming profile was excellent with dimmer output relating closely to light outp

Audible Noise

No noise with trailing. Slight buzz from driver when tested with leading edge dimmers.
