bulbs keep blowing

[garysparky1]

Hi all, myself & another spark rewired a large 8 bedroomed house earlier in the year I got a call recently from customer telling me that bulbs keep blowing in 2 bathrooms 4x G9s and a candle bulb in wall light downstairs. The lights are all on the same bank of MCBs RCD protected and on 1.5m2 T&E. I have thought maybe spikes in supply would be the answer anybody got any other take on this problem, any help greatly appreciated

All G9's from the same batch and poor quality? Mains voltage high? Vibration? Have often had short-lived candle bulbs so that might not be related. Spikes large enough to damage filament lamps will probably damage a whole lot of other stuff, but unusually high voltage will affect halogen lamps more than anything. Are there many other halogens in the property that are OK? What sort of lifespan is he getting from the G9's?

The vast majority of the time I put this down to absolutely rubbish bulbs which don't last five minutes. Are they incandescent type?

I put one in my front room a couple of weeks back when the low wattage one I had blew after about three years. Two days later it was dead.

Not again! Somebody got called out for saying 'lamps' the other day. Call them bulbs in a theatre and you'll never hear the end of it. Let me get this straightened out....

The bulb is part of the lamp which goes in the luminaire but it is also called the envelope and a G9's envelope is a capsule, except in a theatre where it's still a bubble. My avatar shows a bulb that's not part of a lamp, in which the envelope is called a flask, unless the cathode is thermionic in which case it is referred to as a bottle.

Simples.

But it is a fluorescent lamp not a fluorescent bulb, and a candle lamp not a candle bulb, surely???? LOL

OK, could one make a 'lamp' out of a Klein bottle? :smilielol5::biggrinjester:

I'll take your word for it!

Thanks guys, I did say to customer, who supplied all lights, that the bulbs supplied are probably not good quality the ones blown have been in 5 months non are on dimmers they are now replaced with new supposedly better quality ones. Thanks Lucien for your points it seems mainly halogens that have blown apart from the candle bulb.

So we're all agreed that bulbs are for the garden?
