I've just about had it with Levitron devices. I fell in the usual hole regarding wiring the thing in 3 way mode (Nice job with that diagram Levitron !) , now after a few weeks of running, the unit has started buzzing whenever it triggers to the "On" state. It makes the breaker in the breaker box hum as well!

Has anyone used this device to run fluorescent lights? I replaced it with a regular 3 way switch and the buzzing is gone, but I wonder if the unit is oscillating with one of the fluorescent starters. I have another levitron PR180 on the same breaker feed, and that one was humming just like the breaker till I changed the bad PR180 back to a good old 3way switch

There are old post concerning this switch, flourescents seem like a real problem. An Idea I had was a relay so the PR 180 switches relay, and contacts handle fluorescent load instead of Triac or whatever is switching load.
