| 811331 | 2009-09-17 12:49:00 | No way, this is a problem of over voltage from the supplier. | zqwerty (97) | ||
| 811332 | 2009-09-17 15:26:00 | Its the cheap lamps bought in from Asian countries especially from Indonesia. Buying heavy duty lamps helps or those rated for 250 volts. Only real solution we find is to recommend the power saving type. The el cheapo lamps blow when you turn them on in the early hours of the morning and the voltage is higher, when a door slams or even a truck going up the road and shaking the house. Best I investigated was a report that when ever the stereo was turned on several of the lamps in the house would blow at once. It was a real good stereo. The filaments inside the lamps are very weak and poorly supported so are susceptical to any vibration. |

| 811334 | 2009-09-17 21:41:00 | The house that I am talking about has given up using cfl's as they don't last as long as ordinary filament bulbs, I use the very same type bulbs in my house both cfl's and filament and they last me for years. Either the voltage supplied is too high at times or someone is loading down one of the phases and causing big fluctuations on the other phases. I think it is due to being next to the substation transformer that is the problem, to keep the voltage within limits at the far end of the street they have set it too high. I have analyzed this problem over the last 12 years and it is definitely happening. I just let the owner use my daughters F&P SmartDrive after the last of 2 washing machines blew the braking release solenoid coil for the third time and after a week of use the SmartDrive triggered the circuit breaker, and is now dead, they are washing all clothes by hand in their bath at the moment, have been for the last 2 weeks, they've run out of money and so far I haven't had time to see if I can fix it as I have done with a similarly faulty Gentle Annie. |

| 811335 | 2009-09-18 01:07:00 | Funny how F&Ps first autos from the 70s like the 272, 400 and 380 are reliable to the extreme and 10,000s are still going around NZ. The replacement Gentle Annie, smart drive later versions are unreliable and only last about 4 years before crapping out. And the bills to repair exceed the value of the machine. For the bulb blow you might have a high resistance or bad contact in the bulb batten holder just change it (remembering to to turn mains off) |

| 811337 | 2009-09-18 01:47:00 | "RS" lamps (the ones made for trouble lights and the like, hence Rough Service) have heavier filaments so can stand a bit more friskiness without too much difficulty. The El Cheapo lamps are made with flimsier filaments, to keep the cost down, and will die if someone demonstrates that they have been eating beans, closed or door, or usually just turned the fool things on. They are also rs, but a different rs. The good lamps cost more, but they are far less trouble. You could try a lighting specialist or an electrical wholesaler and just ask for RS lamps, or better grade CFL's if those are what you turn on to. Cheap lamps are expensive. |

| 811338 | 2009-09-18 04:05:00 | We had one of the main rooms lit with a 100Watt bulb, it lasted for a while but that's because it was operating on a dimmer, now that the dimmer has blown because the bulb failed short circuit and burned out the dimmer the new bulbs we put in are blowing quite regularly again, they can't afford a new dimmer just now, you know how much they cost these days? >NZ$70, daylight robbery, I am really sick of the BS about the free market reducing costs. | zqwerty (97) | ||

If you're sick of capitalism, then move to North Korea. On another note, you could try picking up a 2nd hand dimmer switch - there's a listing on Trademe for one (as part of a whole heap of 2nd hand electrical switches) for $18. |

| 811340 | 2009-09-18 04:57:00 | Is it only that specific light - i.e. do other lights elsewhere in the house suffer from the same problems? Its only that bulb, everything else in the house is fine, i have tv and home theater setup on a power socket and sometimes a oil heater as well and it never pops or does anything out of the ordinary, i even stole some of the bulbs ive used out of other rooms which has been fine for months and then they pop |
