lamp flashs when i turn off switch

[bluesky]

i replaced a incandescent bulb with a energy saving lamp, but the lamp keeps flashing, i checked the voltage in the ceiling rose, but no voltage at all, how come the lamp keeps flashing?

i have to use the incandescent bulb again.

anyone has come cross this before?

cheers in advance

it is on a dimmer ???

 

[bluesky]

no, just a normal switch

 

[confused-fuse]

it flickers when you\touch the switch or when you turn it on off ??

This is a common problem especially on 2 way lighting circuits wired in the conventional way.
To rectify this you need to rewire the switches to the conversion method to elminate any induced voltage or fit a snubber into your light fitting.

 

[wattsup]

the simple answer is induction, the long answer is capacitance...is the light 2-way switched? is it a particular long run from switch point to to light fitting, is the switch wire/s bunched with other cables. Is there an earth wire in the same switch feed, is the earth wire a 'good earth'

low energy are crap btw ...problems, problems problems...and dim -

beat me to it sintra!

hi, thanks for your replies,

this is a one way light switch, the other lights in the house can work quite well, no flickers, only one keeps flickering when turn off swutch...

isolate lighting take pendent apart make sure the wires are not loose or try another lamp might be faulty check switch as well ..

 

[confused-fuse]

errm is this a old house ??? wonder if you have negative switching i have seen it once energy saving lamps flicker and it was all swopped over worked then .. somthing to do with + side of the sinewave that makes the lamp flicker

Is the switch faulty try a new one.

 

[jas01]

there are certain makes of low energy lamps that have this problem

 

[nickblake]

I had this problem with a mirror light in a bathroom ,found that the light connections were incorrect and the L an E were reversed so may be worth while checking the polarity of the fitting , or its a dodgy lamp

 

[gaffer]

Is it one of those cheap LED lamps?

?

very intrigued by that - you got zero volts between line and neutral, and line and cpc?
