Dimming Performance

RMT500: Minimum brightness from off: 2% Minimum brightness from max: <1% RAK4-T: Minimum brightness from off: 4% Minimum brightness from max 3%

Smoothness of Dimming

When tested with trailing edge dimmers this lamp and ballast combination performed fairly well. The dimming profile is linear with no large steps when fading from 0-100%. It does however have noticeable small steps while fading between levels. All three lamps performed consistently with one another throughout. The turn on when used with the RAK4-T is abrupt: use the step up arrows next to the channel slider when setting scenes if a dim setting is desired.

Audible Noise

No audible noise when used with trailing edge


Not suitable for leading edge dimming: lamp flashes from 0-20%
