Do they glow dimly for just a while or permanently when off? When current is off, they might glow for a few seconds, but then should be off! If they glow permanently, you are getting some leakage from somewhere. IMO that is. ?
Yeah we agree on the leakage. They glow dimly all the time when off. We figured it must be syncing current to neutral and the hot leads must be getting a small amount of current from someplace...possibly induction. We wouldn't have noticed with incandescent bulbs.
Would be interesting to test the socket with voltage tester when turned off. (or have it tested). Also might check to see if a 3/12 line enters the light switch box. (often used to reduce the number of lines coming from the main fuse box.) If there is, then you might have induction of current from the extra line. I am not an electrician, but had a recent failure of one circuit from a loose wire nut on the third line of such a circuit. When discovered, (in a wall socket), the loose wires had finally separated enough to spark and finally burn the wire ends, and the nut and that station lost power, without tripping the junction breaker. Could have burnt the house down. That wire was split at the circuit box, so there were two separate breakers serving two different areas of my house. If that sounds confusing,---it is. But it happened in this house that
I have lived in for 21 years. Your electrician will know what I am talking about.
