I have a 600W Lutron Spacer remote control dimmer unit that is driving 10 4" in-ceiling light cans.
Each of the cans has a 50 watt bulb.
The problem is a very high-pitched whine or whistle that is emitted from the dimmer unit when the
lights are dimmed below a certain brightness.
Above approx. 1/2 brightness level the noise goes away.
It's generally not intrusive unless the room is quiet, i.e.,
silence during a movie or musical passage but it still bothers me that there is any sound at all.
Is this common? Would a dimmer with a higher watt rating solve this?
The lights are a mixture of halogen and incandescent.
Would switching to all halogen bulbs help solve the problem?
An electrician did the install so I'm assuming everything is wired correctly.
TIA for any assistance.
