I believe that dimmer switches cause hum, so be sure not to use those. Beyond that I'm not sure if low voltage lights would be an issue or not, but I'm sure some of the knowledgable folks on here will have some thoughts.
Will low voltage lights cause audible hum?
I'm about to install recessed lights in my listening room, and my interior designer and my electrician are recommending low voltage lights. I'm wondering whether the transformers in them will hum and raise the noise floor in the room. Anyone had experience with this?
