    Advice on LED inductive voltage preventing LEDs switching off

    OK, thanks for all of your help. I understand that the glowing halogen has killed the induction theory, which is a shame because I felt that was probably curable. Ironically I did change some LED bulb brands and when they didn't glow I thought it was solved, but on removing the halogen they...

    Advice on LED inductive voltage preventing LEDs switching off

    Thanks for telling me why - but if you would bear with me I think I can clear up a lot of your points... The crossover/intermediate switch was assumed because there are 3 switches so there has to be one, right? When asked to disconnect a switch I picked the middle one. The original CFL lights...

    Advice on LED inductive voltage preventing LEDs switching off

    Thanks, but I'd like to understand what I've found out so far... I think with the suggestions above I've disproved miswiring in the ceiling (ie anything after the crossover switch), and with a 3mA current when 'off' I think it's proved to be either miswiring before the crossover or capacative...

    Advice on LED inductive voltage preventing LEDs switching off

    Actually not sure if that was clear - I'm new to crossover switches so I'll explain it better. I disconnected one wire from crossover switch and a helper switched the lights on/off with the 1st or 3rd switch. When 'off' the lights didn't glow, I put it down to the 'off' circuit being broken at...

    Advice on LED inductive voltage preventing LEDs switching off

    OK, just disconnected the crossover switch and the lamps do not glow in one switch position. Does this prove they are not getting live from a second circuit? Current at crossover recorded 60-70mA when 'on' and 2-3mA when off. I'm afraid I have no idea what to make of that. There are 14 5W...

    Advice on LED inductive voltage preventing LEDs switching off

    OK, thanks for all the replies... plenty to think about. If a G9 halogen shouldn't be glowing then perhaps checking the current with the switch off is the next best thing to do. Also - disconnecting a switch should bring the voltage back to 0V if this is inductive voltage, but it will remain...

    Advice on LED inductive voltage preventing LEDs switching off

    100uF ? I thought I was looking at 1uF... Have you got a link or something I can 'buy now' because I know there's other considerations (X2? 300V etc)

    Advice on LED inductive voltage preventing LEDs switching off

    I just have a DMM and a Maplin analog meter. I guess I'm also working on the assumption that the previous CFLs worked fine with the same circuit (and, possibly noteworthy) when I replaced just the first CFL the LEDs all flashed as (I presume) one CFL took the voltage until it triggered and all...

    Advice on LED inductive voltage preventing LEDs switching off

    No, I haven't... I guess that would help pin down a snubber value?

    Advice on LED inductive voltage preventing LEDs switching off

    Thanks Pete - I'll google them and 'fancy' brands to see if I can find a common factor. Taylor - I wish I had bought the lights a month earlier when there was a local Maplins! In terms of RSC I find the choice a little overwhelming since I'm not sure if the snubber resistance/capacitance is a...

    Advice on LED inductive voltage preventing LEDs switching off

    Thanks - that would be better than keeping the RCD off! Do you remember the brand or type and I'll check to see if they have a trigger voltage or some other keyword that may help...

    Advice on LED inductive voltage preventing LEDs switching off

    Hi, I'm looking for some advice on LEDs that glow when switched off in a multi-switch circuit. Last month I replaced our old CFL lamps with multiple LED G9 'chandeliers'. The living room has a dimmer switch and the 20-odd LEDs all work fine. However the hallway has 3 ceiling fixtures, with...
