Re: squealing lamps



The more they're dimmed the more they resonate. A few things to try.
Look for 130 volt (long life) bulbs. They have a heavier filament. Try
lower wattage bulbs, they don't have to be dimmed as much. Try different
brands. Look at a brand's clear bulbs to see how the filament is
supported - the frosted ones should have the same if the same brand. The
more support the less noise. It's trial and error and NOT related to
price. Some of the 25 cent cheapies have been the quitetest of all.
Westinghouse bulbs seem to be on the noisy side.
