I had the same thing happen. I fixed my buzz by sticking on a rubber harmonic dampaner on the top of the site where it is flat. I then opened the clear plastic casing and put a few drops of super glueon the fibers which held them in place. Sounds like the freezer wrap might take away from your light a littel and make it even buzz even more. A few drops of glue on the fibers and the puting the dampener on and mine disapeared.
