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.
LED bulb still emits light when turned off. I have recently purchased an IKEA LED bulb with G9 fittings, to replace a halogen one. This one. The bulb is installed in a lamp with 3 other halogen G9s in a 3 + 1 configuration with a 3-state switch. up lights up all four bulbs, down lights up only the socket where the LED is. I have found a strange behaviour. When the lamp's switch is in the off position, the LED bulb still emits a very dim light, whereas the halogen ones do not.
