Stephan writes – “I just finished the show in which I used the slip ring connectors. They worked great for my purposes (fluorescent light tubes). I had them running for about two hours straight and no power cut outs. This means the rotatable connection is pretty solid. I also tried running an mono audio signal through the rings but it turns out the electrical connection creates too much noise and the audio gets cut up.” – Link.
