ust bought a couple Armacost 4 ft. slim LED light fixtures -
very disappointed that they cause radio interference when turned on !
It was not a new issue to their customer service - but they just
recommended that I return them for a refund ... :-(
Has anyone else experienced radio interference with LED lights ?
... any fix for it ?
These are otherwise sweet light units - more expensive
than most - and I'd like to keep them.

Some LED lights are worse than others for radio interference. YOu may
just have to take your chances. They are not suppose to by order of the
FCC, but with all the stuff comming in from China lots slips by .

There is no easy cure for the problem other than to cut them off.
