We have 2 60watt bulbs in our bathroom and the switch is a pull cord.

The bathroom only has a bath/sink etc (no shower). An the door is
always wide open. It never gets steamy in the room either.

Now, at least one of the bulbs blows every 2 weeks when the lights are
switched on.. Usually it trips the fuse box, but not always.

Does anyone have any ideas why this keeps happening?

TIA

Harry

Cheap lamps.  Go buy some 60 Watt tungsten halogen pearl lamps at around 3 GBP
each, and they'll last about six or seven years.  I know the ones I buy normally
do.

It could be that the vibrations on the ceiling, or the rest of the room for that
matter, are shaking the filaments in the lamps, so much that they are weakening
very quickly and breaking.  So, is the room under a well used room?  Are there
door closers which make the doors slam?  Are there kids thumping about around
the area of the room?  Heavy lorries passing outside?  Etc. Etc.

Do you have numerous power surges or cut off's?  Is there work being carried out
in the vicinity power the electricity people?

If the answers to these questions is a NO, then it's cheap lamps.  :-)

I would change the pull switch and see if that helps. Poor/old/worn contacts 
on a switch will cause lamps to blow

Are the bulbs too large a wattage for the holders/shades.  Very hot 
envelopes will probably reduce the life.

No, the bulbs we use are 60w and the shades and holders are rated to
100w

It is the original switch that was in place when we moved in 8 years
ago. The bathroom is in an extension to the house so the switch wont
be more than 15 years old. Worth a try though.

Greetings from Norfolk

Have you checked the lamp holders - loose connections or poor springs in the
holder/lamp connection ?
If all else fail, try getting a Negative temperature coefficient resistor
(cannot remember the trade name) and add this in series withthe lamps - will
reduce switch on surge, and not effect light output to any noticeable
amount.

I would guess on a scale of 1 to 10 (10 being very poor condition) the
bulb holders are about a 6. Springs are still firm but they have seen
better days.
