I installed a light fixture that contains 4 dimmable GU10 LED lightbulbs. I also installed a dimmer switch (Feit Electric Model 72200) for the fixture.
When I dim the bulbs to 50-85% on, I hear a distinct buzzing sound coming from the bulbs.
Can the buzzing be caused by a defective dimmer switch, or is it simply a case of poor quality LED bulbs?
Will buying different bulbs likely fix the issue?
