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.
All mains-powered light sources flicker, all the time. So if all lights flicker, why do some people think flickering LEDs are a problem? LED flicker used to occur because â unlike incandescents, halogens and fluorescents â LEDs have no persistence. When the power supply to an LED is switched off, the light output stops instantly.
