I bought an LED light bulb for our stairwell, and noticed that it was glowing even when the switch is off. Current leakage, I though (or badly wired socket). So I took the bulb out - and it still glows for a couple of hours.

Like perpetual motion
only lighter

It can only be capacitance, or resistance or inductance - and it sure as tulip aint resistance. All you need to do is rule out which one of the other two it is.Originally posted by NotAllThere View PostI bought an LED light bulb for our stairwell, and noticed that it was glowing even when the switch is off.

Probably for the same reason a neon lamp glows when it is connected to hot (and nothing else). LEDs respond to very low levels of current, the kind of current you might get when there is a slight capacitive coupling to earth (which is pretty much everywhere). Sometimes electronics isn't as straightforward as it seems.So this guy thinks it could be capacitance or inductance. I'd tip on inductance, and the possible RF could be anything, like your NAT router. Either way you are unlikely to figure out what it is, but strapping a 1mic cap across the beast in parallel will probly sort it out. Why not try it and write off to the vendor requesting a mod if it worksIt is responding to radiated energy, possibly 60Hz, possibly RF from a local radio station (I'm betting line frequency). A capacitor will divert the energy around the LED.

I had a fluorescent light in my bedroom as a teenager. That would glow after an evening's use if I touched it.Originally posted by NotAllThere View PostI bought an LED light bulb for our stairwell, and noticed that it was glowing even when the switch is off.
