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.
No more humming and flickering&mdash;and much better color rendition from the higher quality T-8s. Flickering fluorescent lights are caused by the starter not being able to fire gas into the tubes. You will need to remove the bulb to get to the starter, which is a round plug sticking out through a hole. Itâs either been unseated, or itâs defective.
