I am certainly not an expert on such things, but I've also been of the
understanding that one way to "dim" LEDs is to pulse them - turn the
electricity on an off - the more "on", the brighter they appear, the
more "off" the dimmer they are.
I believe that some of the newer cars with LED tail lights work this way
- tail lights operating "dim", and full on for brake lights.
Or I may be completely wrong, and that doesn't solve the problem of
dimming the LEDs based on a wall switch mounted dimmer...
