LED Lights staying on without power

[Stuart Lane]

I have just put up some new lights with modern LED bulbs - the ones with spaded ends. When I turn off the switch the bulbs in the upstairs landing light stay illuminated, but not as brightly as with the power on. Has anyone seen this before - have I wired the light up wrong? The other identical one at the bottom of the stairs is working normally.

Very common. Capacitance between the wires of two way switching.

Try a better class of led lamp including snubber for the induced current causing the glow.
You pay your money you take your chance.

I had a similar issue before Christmas -
after removing a pendant light fitting and installing 5 led downlights on a new dimmer. All GU10 lamps glowed ever so slightly when the dimmer was turned off.
I thought it was caused by induced voltage from other cables in the void so installed a neon in a MF box connected to the last downlight to absorb the voltage but the lamps stayed the same. I upgraded the dimmer and this had no effect. I changed the GU10s to better quality and this solved it. If this hadn't sorted it, the next step would have been to install a low load capacitor.

Note that this residual glow isn't a problem or an indication of a fault, and could even be considered a bonus in an upstairs corridor. A free night light.

New method of emergency lighting, only works with the power on.......just flick the switch to 'off' to test. ?

Eddy current between 2 way conductors. Cheap lamps too!

Thanks for all your replies - I thought it might have something to do with capacitance or induced voltage and also being a 2 way light circuit. Wiring of both lamps is identical and I knew it wasn't necessarily a circuit fault. Lamps probably are cheap ones but they came in another light we bought. I'll just leave it for now and play around when I have time. I thought it might shorten the lamp life you see but maybe not?

Judt to add to my able colleagues advice. It’s called ghosting.

Fit one of these across the mains connection to the light fitting

Thanks Taylor. I might just do that ?.

I put different bulbs in and guess what - the problem has gone away!

 

[Taylortwocities]

Yes, that’s often the way. Not all lamps are made the same, some have better / different circuitry.
glad it’s sorted easily.
