LED Lights still glow when outlet turned off

Known problem with the older Leviton models although the newest ones are supposed to solve the “low glow” problem.

Easiest way to solve it is to add an extension and plug a night light with a 4W bulb or a phone charger into the other side as that will generally raise the current just enough to cause the outlet to turn off fully.

I know it sounds weird, it just has to do with some technical issues. It comes up every year around this time as people use these devices for Christmas lights. See the following thread
