LED light keeps glowing even when "off"
I needed to replace wiring on the second floor our house. A licensed electrician owed me a favor and helped out, with me doing the bulk of running the wire. He supervised or did the hook ups. We installed a new LED ceiling light fixture in the bedroom. The LED is built into the fixture as a ring of diodes, no light bulbs ever needed. Installation was easy. However, even though switched off, it gives off a ghastly glow all night. Very faint, maybe a tenth of a candle power. Sort of a glow in the dark that never fades away. Electrician tested and rechecked everything. He says there is some miniscule voltage "leakage" or natural stray voltage that causes it to glow. No big deal. He explained that such things happen frequently near high power lines, or for other reasons. He took a light bulb out of his pocket and set it on the table. Even it glowed a bit without being screwed into a socket.
Anybody else experience such a thing?
