| 811343 | 2009-09-18 05:32:00 | I'll bet there is water running down to the light fitting from a leak in the roof :( Yep. You could be blaming the symptom rather than the disease. Suggest you do some more checking.:thumbs: |

| 811344 | 2009-09-18 05:37:00 | Not my house though, so Im not gonna spend a second of my time in the room. Il see how it goes, if its a problem then il get in contact with the landlord otherwise just keep buyin bulbs | hueybot3000 (3646) | ||

| 811346 | 2009-09-18 06:08:00 | If it's only that socket that would suggest some kind of wiring problem I expect. Not sure what kind though. Could be a loose connection (just found this): A loose connection in the lamp holder can also cause bulbs to blow. This is because the circuit is not completed as tightly as it could be and the electricity may have cause to "arc" or jump across the contact, rather than simply flowing through it. When this happens it produces more heat in the fitting than is expected or catered for by the bulb, and the bulb can blow. The same can happen if the spring loaded connection in the bulb holder is slightly loose. This will cause electricity to arc across the contact, cause too much heat and blow the bulb. This can very often be diagnosed by looking at the contact on the bottom of the bulb to see if it is pitted. Arcing electricity effectively melts the metal it is arcing onto ( This is how arc welding works) so if the bulb contact is being subjected to arcing, tiny little indentations occur, called pitting. It is sometimes possible, if the live connection in your light switch is a little loose, for this to happen here also. Heat will be generated and it is possible, though very very remote, for the bulb to blow as a result of this. You should probably get it checked by a qualified person before something catches fire. |

| 811347 | 2009-09-18 10:01:00 | Years ago when I was an electrician on the tools I came on this problem a few times. In my opinion it came down to three things High Voltage, Vibration & Heat. As stated in another post, the voltage at houses nearest the Transformer will be higher than those houses further away. If it were not so, then the houses furthest from the transformer would have a voltage too low for some things to work. The TV would be a good example. That doesnt explain, tho, why only that one light fitting is a problem. One thing you should NOT do is move a bulb from another light point to the suspect place. The filaments get brittle & dont like being moved, they break. Vibration. This will also cause the filaments to break. Can be a thump on the floor above (If this has a floor above). Temperature is another possibility. If the bulb is in an enclosure it might br getting too hot. Have a look at the "Pins" on the bulb base. Are they normal? They may well be tarnished but thats ok. They should not have burn marks on them. I agree with the "Rough Service" bulb idea. It has more filament supports that an ordinary bulb, the light output will be slightly lower. If the worst comes to the worst then abandon that light fitting & use a standard lamp or somesuch. Seeing as you will possibly only be there for another 4 months. PJ |
