I have been searching the internet and StackExchange for a couple of weeks now and have not found anything that fixed the issue. I recently added a room in my basement, all new wireing, lights, switches. when i turn the breaker on to that room all of my led lights glow when the switch is off. when i turn the switch on the light come on as expected. i have read where people say this is due to the minimal current that is usually in your circuits when off, and they said to put a regular light bulb in one of the sockets and it will act as a resistor and dissipate the remaining current. i just tried that tonight and the leds still glow( all 4 lights) Below is how they are currently wired for reference. Any help or ideas is appreciated.enter image description here

    what kind of a switch are you using? .... is the outlet really switched?

    thanks all for the replies, @Harper i doubt that the switch is anything other than an ordinary switch. The first one i used was a simply 2 pole switch from Menards(cost like$1.50) usually a smart switch will cost more. Also i think that i already said somewhere that i plugged a incandescent work lamp into the outlet and the LEDs all still glowed.@Ken the 4 foot shop light is the Walmart brand shop lights, i dont think that they are made on an fluorescent fixture, but the other light still glow either way.

    Does the switch have an illuminated toggle?

    The switch does not have a illuminated toggle. As stated a few times it is just an ordinary single pole switch

    @dandavis LED lighting solutions for the home use a Power Driver that controls current , much like a resistor would but resistors have several issues which is why they are not used. Your LED's in the home like the op's normally have internal power drivers which can range in frequencies even up to 2MHZ. While they might be plugged into a 50-60hz source they do not operate at 50-60hz internally they rectify that AC into DC and the power driver then uses FReq and PWM to control the current and voltage supplied to the LED's -many reasons why this is, far too much to discuss here.

LEDs need very little power (that is the point after all). In fact, if you have a live cable running next to a cable feeding the light, then there can be enough inductive coupling between the cables to cause a glow.

The fact that you say "I tried to seperate the 'main line' as much from the lines feeding the lights and it seems to have worked for the most part." makes me think this is the explanation.


I have it happening with certain (probably very sensitive/efficient) LED bulbs in the house. My guess is that there are very small amounts of current leakage in electrical systems (even switches). Certain LEDs can give a bit of light using that current. I just accept it...it's a bit of nightlight in the room and added electric bill has to be extremely minimal.
