OT....light dimmers and question...
I installed three light dimmers this weekend in three different rooms (one being where home theatre is setup) and all three of them have a very low 'buzz', especially when the lights are dimmed the most (just barely on), but still have a little buzz when at their brightest setting. In all three rooms, the dimmer is controlling between 5-7 recessed light fixtures in the ceiling. Any ideas why there is this buzz? The buzz is constant and when watching tv or listening to the radio you can't hear it, but if the room is completely quite, it is there.
Thanks...advice from Lutron...
The dimmers I used were approximately $20 from Home Depot and are made by Lutron....I talked to them and they recommend using bulbs with a life of 3K-4K hours....since each of my dimmers is controlling between 5-7 recessed bulbs, the more inexpensive bulbs (which I am sure my buider used to cut cost) have flimsy filaments which 'rattle' when turned on and off quickly. I am sure this is it....all the bulb filaments 'rattling' and having many doing it at the same time results in the 'buzz'....audio equipment is not buzzing...
