Re: LED's glow when off most likely it is circuit leakage of the light itself. A fraction of a milliamp can cause an LED to glow but not put out useable light and the amount of energy used over a year is probably just a few pennies so I wouldn't put a lot of effort in trying to fix it if that is the issue.
The newer ones use less than a dozen high output LEDs, the older ones produce lots of light by having as much as 300 LEDs. Its with the older LED lamps that the light doesn't stop after power has turned off, it dims a great deal but there is still visible light for up to a minute after. 1 following. 5 answers 5.
