LED Lighting Issues

[nigelp]

About 6 months ago I bought some 1w GU10 LED light bulbs on e bay which I am happy with and they work fine - dim, but thats what I wanted. I have just purchased some more from Screwfix and have some issues. To cut a long story short, whenever the Screwfix bulbs are in sockets that can be operated from two switches they remail lit albeit very dimly. When in sockets that can be operated from one switch only they work fine. The e bay bulbs work fine in any socket as do the standard GU10's. None of the switches are dimmer switches. Not sure of the relevance, but if I turn all circuit breakers off except the one in question the problem remains and yes it does go out if I trip its circuit breaker. The house is fairly new (15 yrs old).

Any ideas gladly received!!!

Inductance and/or capacitance in the cables.

Presumably you mean ind or cap remianing in the cables. If it is, is this normal/ to be expected and if so, presumably the bulbs should be designed to operate at a higher threshold. I did check for any residual voltage with a voltmeter (ac) and couldn't detect any.

Thanks for the response.

The same problem is encountered when using some compact florescent units the voltage builds up and makes them flash every round again.
I think some bulbs cheat and fit a resistor which stops build up.
But can't really blame the bulbs.
I have also found the angle behind some of the LED and Cold Cathode lamps will not allow them to be fitted in some holders and in some cases stick out and there does seem a lack on designers point to make the holders future proof to fit energy saving type lamps.
Only cure is use different bulbs.

Thanks, was a it of a head scratcher this one. Got round it by putting Screwfix bulbs in sockets only operated by one switch, although am sure they would have taken them back anyway. Appreciate the info.
