flashing light bulbs
« on: 22/08/2007 21:18:00 »
I notice that when i use dimmed lights, ie i dim the lights. The bulbs seem to get brighter, then fade, brighter, then fade every second or two. why is that?

I have the same with mine....eventually they just go out !..in fact..I can't have them without top brightness or off !

In my case I think it's a faulty dimmer switch but in your case it may be something quite different !!

i was hoping that was not the answer, although i have dimmers in all rooms and they all do this.

In that case it can NOT be a faulty switch if it occurs all over!!..it's just too coincidental (unless it was a faulty batch and they were installed all at the same time)...... ....I have it other rooms too and it only happens in one room !..
I hope you get a resolution.

Are the lights ordinary tungsten filament?

Hi Paul
It's OWNER of Sophie, asamatteroffact.
(Husband of Alison)
As far as the dimmers are concerned, I think it must have been a dodgy batch that you fitted. I did have the same problem with an old dimmer and just changed it. You could try changing just one dimmer and see if that works. Otherwise you will need some root of hemlock and a toe of frog . . . . Is you house built on the site of an old Indian graveyard?

1. So, did changing one dimmer have any effect, Paul?
2. Yes, you're right. Sophie is a Westerly Centaur (yacht, 26ft long, elderly and spacious).
Was out on her this weekend in Chichester Harbour; very relaxing.

1. No, i have the same "problem". I very rarely use lighting at home so i can live with it, i just think it strange. unless, as you say, i have a dodgy batch of dimmers.

2. yes, i am right!

Dimmer switches on tungsten filament bulbs reduce the temperature of the filament and the bulb's efficiency they also make it very susceptible to small voltage changes so if you live in an area where the voltage is not very stable for example in a semi rural area where electricity is supplied via mains voltage overhead wires the lights will tend to vary a bit with the voltage.
