I am now using a conventional dimmer with four low energy dimmable lamps, and very happy with the range, consistency and colour of the light. My first experiment with one lamp was a failure. It didn't load the dimmer enough. Most seem to need a minimum of 40W.
Question is does dimming save much energy? I know that with tungsten filament it saved very little as the light was a tiny part of the output. Has anyone measured, or seen figures for, the energy saving for CFLs? My searches have revealed nothing.
