Electric bedside light

[david.cawkwell]

Hi group,

I recently replaced an old blown non eco friendly light bulb in my bedside lamp with a new eco friendly one. Same light less watts.

At night now with the light switched OFF! The bulb is flickering just a little but enough to see in the dark. I am not near any high magnetic fields and I have other low energy in some of the ceiling lights of the house but they don't do it.

I've had to put a high energy bulb back in as you can't sleep with it like that.

Is it a pointer to some earth fault in the house wiring affecting the sockets of the bedroom. I haven't tried the lamp in other sockets around the house yet.

Any ideas what is wrong?

Hi

Live / Neutral could be swapped at the socket, or the switched wire in the lamp may be connected to the neutral instead of the live.

Worth checking...

Its a known problem in some cases - usually on lights that have a long wiring run. The voltage induced in the wiring can be enough to slowly charge a capacitor on the input circuitry of the light - and every so often it accumulates enough charge to power it up very briefly.

Probably nothing to do with your earth.

Check the switch is not wired in the neutral of the flex or the plug wired with L & N transposed.

I know the plug is ok as I wired that myself. I'll start checking stockets in the same circuit and see what is what.

The most likely culprit would be an inline switch if it has one. Very easy to swap the polarity on these and leave the live permanently connected to the bulb.

Is the switch in the right leg though?
