Thanks Ken and John,
The bulbs are just your normal white colored 60-75 watt bulbs you buy at walmart, I think they are GE, nothing expensive.
I'm puzzled because this static sound shows up in the tweeters when the switch is OFF, not ON. Also, being on a different circuit puzzles me. Now in the breaker box, these two breakers are next to each other, not sure if that would play a role. When I turned off the 15 amp breaker for the lights in the rec room, which includes the close light, I still hear the static. It is only when the circuit is active and the lights are ON.
Weird.
