I recently connected a mains smoke alarm from a light fitting with 3x50w halogen spotlights in by using a junction box to break into the permanent live. All was well until I replaced the bulbs with low energy ones. Now the low energy bulbs pulse very slightly when the power is turned off and the smoke alarm occasionally goes off without explanation. Any ideas?

yes, dont wire the smoke alarm to the same cct as low energy lamps.
regretfully i am being serious.
did it happen with halogen lamps (probably not)
there is a whole topic on here about cfl's pulising when installed on 2 way switching

It was fine with the halogens and it is at the top of the stairs, so it is on a two-way switch. I will try and find the section and have a read. Many thanks.

i wish you luck with the new search facility, i think the resolution was "tough", there is not a lot you can easily do.
its do do with the cfls themselves

i never said or implied there is was / will be any harm (unless you are an epilieptic)
Bung a cap across the lamps, will stop the pulsing issue.

thats easy for you to type, but what value?
Damn, I KNEW someone would ask. I've had to go and trawl thru my storage and its raining out there.
I have previously used 0.1µF 275vAC rated capacitors. Works well.

Last time I played with capacitors it was with 5v, not sure I trust myself with mains voltage. Where does it have to go across?
Although it is 2-way switching there is just a switch live and neutral at the fitting so there must be a junction box somewhere?
I think I will just put halogens back in!

It will go between live and neutral.
If yr more comfortable putting back yr halogens, go ahead but there will come a day when we all ahve to use more energy efficiant lighting and there will be lots of probs like this to deal with (and lots of dimmers to take out as well!)
