light bulbs keep blowing

[R G]

Half the time the fittings are the issue , had a few calls and see old story lamps keep blowing , the very narrow design of the shades and the downward facing ones are the worst , usually having golf ball or candle lamps , the heat can't dissipate , quite often I find the caps have been left in the fitting where the heat has separated it from the glass and when you get it out the colour of the base shows the lamp has been subject to excessive heat , the answer always has to be LED lamps to reduce the heat ...

First post on the forum so be gentle!

Just to add a personal experience to this thread, although poor quality lamps could be the issue, I did find that a loose connection in the circuit was the reason for frequent lamps blowing on a job. Possibly due to a higher than expected current being drawn through the filament, although not as bad to trip mobs.

Try 250v lamps

I was drinking with a retired engineer recently who swore the most common reason for filament bulbs going is people walking around upstairs making the filaments wobble... May be some truth to this?
I investigated a house last week where the "LED candle bulbs kept going every couple of weeks". In the end it was apparently 2 bulbs that had gone, not LEDs and not screwed in tightly (and candle bulbs as well).

If I got paid for the amount of times customers have (unwittingly) mis-led me I'd retire tonight

Had a DIYer this week who I 'suspect' connected a yellow (off 3-core) light cable to the cpc when moving the switch out of zone (without RCD protection) then forced the MCB against it's will, under fault, breaking it & nearly burnt the whole system down. Apparently he "just replaced everything in the switch like for like". Hmmm
