I have 14 Lutron Maestro MALV-600 dimmers controlling all my recessed and track fixtures. My track fixtures are Lighting Services Inc. (LSI) CX16 (12V, MR16).
For the first two months I lived here, all was well. Then we had an electrician come in and install two sconces and move four outlets (working on several different circuits). And all heck broke loose.
Ever since then every single Lutron dimmer I had has exhibited the following behavior: Lights are on. They starting strobing off (hard drop) and the gently coming back up in typical Maestro fashion. Once back on, they shut off again. And repeat. And repeat. It doesn't always happen. I can't really determine why or when it starts. Once it starts, it will continue until the dimmer is turned off. The other M dimmer on same circuit joins in. Sometimes it will continue afterwards, sometimes not. I have videos of the behavior that I can post to YouTube if that helps.
The electrician is telling me that it's because the dimmers are magnetic and they all need to be replaced. He cannot explain why all was stable until he started working here.
Can anybody help before I spend a ton of money on new dimmers????
