OK Axiomites, I need some creative thinking here. ( wise cracks invited)

Since I've got the EP500 I've had alot of Rattle in my room (NO its not in my head...). Anyways, I've managed to eliminate/minimize most of this except a buzz coming from my pot lights.

Now I have tightened all the nuts and screws on the pot itself and added felt between the finishing fixture and the pot itself so all I can think of that's left is the flood light itself. I seem to beable to stop the buzz if I place my fingure on the flood light so...

What I'm looking for is either something commercially available or a creative idea of using something that I can fit between the flood light itself and the pot light fixture, in order to dampen or stop the movement of the light. This obviously would have to offer some insulative property...

Are there any kind of spacers or fasteners available for this kind of application?


Any thought of what I could use in a more permanent way...?


Thanks for any ideas, Jag
