Don't be so dismal Dick, Ben said;
LED lighting fixtures in general , like fluorescent fixtures, cannot be dimmed via reducing the voltage to the light like halogen and other incandescent bulbs are dimmed. The dimming scenario for LED's has been the biggest holdup in their wide-spread usage in high-end coaches. Special circuitry is required to dim them that reduces the current flow, NOT voltage to the light.
It is very probable that Millennium's quality product will be reflected in the use of the expensive current limiting dimmer and not the ordinary voltage reducing dimmer.
