A lamp? Not sure I buy that unless there is a faulty connection arcing and sending out RFI. Or a faulty LED lamp - maybe. Will be interesting to this diagnostic tool they promise will be coming next month.
Oh great, yet another excuse my provider can use to say it's not our fault. Wonder how much this "tool" is going to cost?
I expect that the supposed issue is about the electrical interference, not the light itself. Though I have never had cause to research the issue, so I don't know how much of a problem this would actually be.
