Flashing Led's And Voltage Optimisers

[ajheis]

WOULD ANYONE HAVE ANY PROBLEMS/ISSUES WITH LED'S (IN THIS CASE GU10'S) WHICH FLASH/PULSE INTERMITTENTLY WHEN SWITCHED OFF?  A FRIEND OF MINE AND A NEIGHBOUR WHO LIVES IN SPAIN IS HAVING NIGHTMARES WITH THEM. THEY ARE IN 2  NEW BUILD VILLAS WITH 3 PHASE SUPPLIES AND CANNOT CURE IT. NO DIMMERS IN CIRCUIT JUST THE ON/OFF SWITCH. I AM GOING OVER TO VISIT AND WILL HAVE A LOOK WHILE I'M THERE. SOMEONE HAS SUGGESTED A VOLTAGE OPTIMISER ON THE MAINS. 3 PHASE-DO THEY HAVE THEM ? AGAIN I HAVE READ ABOUT THEM BUT HAVE YET TO FIT ONE.

ANY SUGGESTIONS ANYONE???

THANKS,

It sounds like capacitive coupling TBH. To see if it is replace one of the leds with a regular lamp and it should stop.

There are a couple of ways of stopping it permanently, the easiest (without being able to see the wiring) would be to fit a snubber

1: FIND THE CAPS LOCK KEY. ITS THE ONE OVER THERE ON THE KEYBOARD <<<<<<<<<

2: well known issue, most likely inductance, as above

Pardon ?

Don't know what the Distinguished Member meant by the reply 'pardon'-maybe he could elaborate?  Any input on Voltage Regulators would be helpful?

Thanks for the Inductance advice. Whats a Snubber?

Thanks,

Look at Danlers Resload or Capload

Distinguished Member-you're either intelligent or obtuse-please if you have anything useful-share the knowledge ?

As other learned forum members have replied, its inductance causing your problem.   Fitting one 'normal' lamp would cause it or possibly a snubber which we discussed here only a short while ago   http://talk.electricianforum.co.uk/topic/20446-snubber-for-leds/   Not sure if the Danlers resload would work in this situation as i have used them to smooth out dimming on a live circuit, possibly they will & they draw 12 watts
