    220 V LED downlighters glowing when switched off

    I have jus installed 6 down-lighters in my lounge/dining area which are switched 2 x dining and 4 x lounge.
    When Is switch off the 2 in the dining area are out completely but 3 of the 4 in the lounge area glow. What can I do to eliminate the after glow?

    Do you have a dimmer in this circuit?

    No, just straight 220V led.

    Change the switch for a 2-pole and switch both the live and neutral (assuming the neutral is running though the switch)

    There's also the option to install a snubber (bleed resistor) either at the switch or at one of the lights.

    You can also use a 2-pole 230v relay at the first light fitting. The light switch is wired to operate the relay and the 2 poles of the relay then switch the live and the neutral to the lights. This is a belt and braces solution because firstly you're switching both live and neutral and secondly the coil of the relay also acts as a drain resistor.

    There are also other ways of wiring a light circuit switch which....whilst they're maybe not illegal, certainly aren't orthodox and best only used as a last resort so I won't get into them here.

    **Edit**

    Just a word of warning, if you're not an electrician you should get one in to do this work. All the solutions above assume the circuit is correctly wired, safe and free of faults. Before assuming the glowing LED's are caused by small induced voltages which would be addressed by the methods above you need to test the circuit, specifically the IR values to prove the problem isn't actually a symptom of a more serious underlying fault.

    Thank AndyD. I will most certainly get an electrician to sort it.

    Sorry for the late reply. The electrician has put in a snubber and the problem has been resolved.

  7. Thanks given for this post:

    Hi
    We have come across similar problems and it has been caused by a switch which has LED indicator - We have found the indicator to have been connected incorrectly allowing a slight "leakage "

    you can also install a small capacitor at one of the lamps

    We have also been encountering a similar problem...LED downlight flickers when switched off...on 3 occasions we found it to be the same make (Ellies) ...replaced the lamp with a different brand...problem solved.

    I had a similar issue today with major tech LED indicators, there are wired to be on when the light is off, as a result there was a constant 35v on the load side of the switch even when off. A bleed resistor did the job.
    I think these switches would be so much better if they had 2 poles so that the led indicator could be separate from the load. double pole relay could sort it out too, using NC for led indicator and NO for Light load
