Singing light bulb on dimmer switch
Gosh, gee.
If we are worrying about lights bulbs 'singing/humming' it makes one wonder
what other RFI (radio frequency interference) these somewhat unecessary
devices are causing? Why not use cheap bulbs and turn off a lamp or two?
And since many (most?) dimmers are manufactured 'to a price' is it correct
to assume that compromises are made?
