I have just had a dimmer switch installed in my dinning room, the only problem is that it buzzes, the higher the light brightness the loader it is.My electrician says this is normal, I find that hard to believe.
Is he right?

As I understand it, dimmer switches don't work well with the new bulbs. I had dimmers in most rooms with the old bulbs without problems, but since the intro of the newer type of bulb, I've done a Waka...gone back to switches - RobSteve Maskery":1eqs4r9e said:I had one in my last house. It didn't buzz at all, but it did use old-fashioned tungsten bulbs.

Paul Hannaby":17krigqv said:Assuming we are talking about the usual filament / incandescent bulbs (most dimmers don't like the low energy fluorescent or LED bulbs), the bulb doesn't flash 50,000 times a minute. The supply is 50Hz so at best, the bulb would flash 6,000 times a minute (50Hz x 60 seconds x 2 for positive & negative cycles). In practice, the bulb doesn't really flash because to do so, the filament would have to go from hot to cold on each cycle to do so.
