Having a problem in a flat where the light bulbs are blowing once every week or 2 weeks? It is a new build flat (circa 2000). Is there anything I should do or look out for?

A chemically burning smell of melting insulation. Something is shorting somewhere. Had this in my house and (ventually) traced it to a badly joined cable chased into a wall, halfway up.

Took it out, rejoined it, properly shrink wrapped it, all sorted, but the very bugger to locate.

What sort of lamps and what type of fitting are they in i.e a pendant or reccessed fitting?

If it's those 50W 230v halogen lamps, then this is completely normal. Don't replace them with el-cheapo ones.

lol as per flaperon - 50W dichroics drop dead regularly, but I'd be concerned if its normal lamps.

Hi,

Is there any pattern to the time of day this is happening? I used to get this, more often in winter early in the morning (5-6a.m.). If you live near to a small local substation the effect can be worse. The voltage can go high in times of light loading on the system. The transmission transformer is supposed to regulate this to within strict limits, but sometimes if can go over, which will cause lamps to blow. I was forever replacing lamps in the kitchen like this.

Or don't because of the mentally high price! £29 a lamp for the dichroics in my kitchen. Take a long time for me to make that back I'll tell you!

cynic-al I'm finding mains LEDs performing better and it's easy to ditch the transformers and swap the lampholders.

Most common cause of failure is worn lampholders (common in LV) and not using Alu backed LV lamps in Fire Rated fittings. As well as some lamps just being utterly terrible.
