I just installed LED can light in a customers kitchen, they buzz, slightly. I thought it might be the old dimmers, replaced with new dimmers and a few still buzz. I have 2 different kinds, 4" and 6", both buzz. Picked them up at Lowe's, house brand. I checked grounding at the  fixtures, dimmers, it was all pretty solid. Anybody else have similar experiences?
