yesterday was working in a house where a different sparky had installed LED spotlights on dimmer switches. the leds flicker when you dim them. also the mcb the lights are on buzzes when the LEDs are on - to do with harmonics I think. But the funny thing is I know another house that was done by the same sparky with the exact same problems. Why would he keep doing that - surely he would have learnt?? and is it only certain combinations of dimmers and LEDs that flicker because I constantly install LEDs on dimmers but they never flicker?
