Flickering LEDS!!! Whassup guys???

[alexg]

Mate, I've just installed 20 LED 5 And 7 watt gu1o LEDs in place of mainS voltage... all operating on a switched fuse (already there!) and... turn it off.. there's flicker!?!?!

No cables running alongside. Although there maybe on the sfy=u load cable as there dare other sockets nearby.

Its doing my head in buddy.

Its a very long run around the customers garden.

Capacitance maybe? If the earth is not now functioning in the fittings would this be a problem v.v disappating the capacitance etc?

Just about to give up!!

THANKS for your reading...

Don't some LED lamps need special drivers? Just a thought, though I'm probably wrong.

Good point Mr Brown but the op says they flicker when turned off.

Change the switch/fsu, its getting power from some where and that is where I would look first.

Well I did say I was probably wrong :goofy:

 

[alexg]

They're mains LED... pluuuuus... I've changed the sfu!

wassup

yikes

And in the wonderful world of fault finding it could also be right?

 

[Paul.M]

Take one of the flickering fittings down, turn off the switch then check across all conductors for voltage. If you've got a current whilst switched off your getting it from some where? Turn off one mcb at a time to find out, then start locating the where the fault is coming from.

 

[alexg]

problem is its in a garden...long run... and the sfu is next to other sfus

cheers!

 

[alexg]

no oer cable next to it... in garden

 

[Jimmyb]

change the light switch, worked for me small voltage passing though when turned off, also had the problem with energy saving bulbs doing the same when wired with 2 switches and the 2 wire strapper method.

hope this helps

 

[alexg]

yup

i changed the swicthed fuse its on and same thing

wtf

This may be me being completely mad but stick your voltmeter probes into the garden soil, see if you get anything. If not blame me for making you look like a twonk testing the flower beds!

On a more serious note, disconnect the switch/fsu and crock clip the outgoing L & N. Whilst the switch is disconnected, test at a couple of fittings. It must be coming from some where?

 

[alexg]

done that unfortunately - was a fused switch

..............

 

[Paul.M]

Have you done an IR test from the fsu with lamps removed?

 

[alexg]

no... if the fsu is off why? sorry to ask!

 

[Paul.M]

no... if the fsu is off why? sorry to ask!

To establish the integrity of the cable.

Ok, with the switch removed do the lights still flicker? If the answer is no then you have a dodgy switch (regardless if you've changed it).

If the lights still flicker with the fsu/switch disconnected then you've got a current in that radial circuit. Switch off one mcb at a time to find out where the current is coming from.

As it is a garden I'm assuming these are IP rated class II fittings, go round with a wander lead and see if you have an earth at the fitting, my guess I reckon you haven't.

Also look at fitting a snubber in the circuit.

Out of interest do they flicker for a long time after they've been switched off, or does the flicker diminish gradually then dissappear all together??
