Apologies for raising this here, but I don't know
another forum where the topic might get taken seriously. These new light bulbs - the ones with the little bulb inside an old style casing - seem to blow very quickly. They don't seem to last anything like the promised coulple of years. Or have I just been unlucky? PS You can get previous Euromillions results on TVE Internacional text page 472. |

Or have I just been unlucky? PS You can get previous Euromillions results on TVE Internacional text page 472. Presuming you mean halogens - usually rated about 20% less than the GLS equivalent, i.e 48W halogen for a 60W GLS? They should last better and longer than a conventional bulb. It is unlikely you have been unlucky assuming you are buying a decent brand, so there are two options: either you have very spikey mains, or you have poor quality light switches. In terms of the latter, a halogen bulb has a relatively high inrush current when first switched on. If your switch contacts are old and/or bouncing (and possibly arcing) it can easily blow such a bulb. Try changing one switch where bulbs regularly fail for a good brand such as Crabtree or MK and see what happens. -- Woody harrogate three at ntlworld dot com |

The bulbs are in table lamps which have been in use for ages. It looks like I should get new lamps - or else go back to the spiral flourescents. Thanks again. |

Actually they are famously fragile, those halogens. Because the filament is so short compared with the filament in a normal bulb, it has to be ultra-thin to get the right resistance. That's why they are so delicate. For 12V applications the filaments are really tough because they are thick. For 240V it's a different story. I've read somewhere that it's mostly subtle vibrations from the floor or ceiling that does them in, although I don't know for sure whether that is correct. The energy saving is so minimal it isn't worth using them, in my opinion. LED lamps are becoming available now (B&Q, IKEA, online) and I've got them in my table lamps and uplighters. Wonderful, so long as you make sure they're "warm white" or 2700K. -- SteveT |

Just hope that you have no AM listeners or radio amateurs nearby as they create horrendous RFI and are known to flicker in the presence of RF (they are diodes after all.) -- Woody harrogate three at ntlworld dot com |

I've read somewhere that it's mostly subtle vibrations from the floor or ceiling that does them in, although I don't know for sure whether that is correct. I moved away from 70W halogens in my living room pendant because they would blow with someone thumping around upstairs. Tungsten and CFL have both been OK. I recently switched back to halogens when I got a couple of 120W ones (equivalent to 150W tungsten) and not had a problem, but I've no idea if that's because the higher wattage necessitates a thicker filament, or the lamp is a better quality brand. |
