Ceiling lights keep blowing?

Question

No cheap bulbs here. The circuit that runs from my kitchen to the laundry keeps blowing out. Bulbs last max 3 months, even the long life ones. I recently had to replace a light fixture and noted the old fixture wasn't earthed correctly (screw was hitting wire casing, but not connecting). Could this lack of earth be the cause? It only appears to be this circuit as well, everything else in the house is fine. Electrician is the obvious solution, but their is a shortage of service this time of year - December 22 is the date I have one booked. Any help now is appreciated.

Answer 1

if stop and think about it , the voltage at the switch most of time is about 122-125-6 volts and if put in a bulb that is rated at 120volts , the bulb is going to burn out soon because u r appling more voltage than what the bulb is rated for sooo,,
if u put a bulb that is rated for 130v it will last a long time.
but u cant get this at the grocery store but u can at a electrical wharehouse just ask the counter guys.

Answer 2

If you have 3 wire - 120/240 volt utility service (or something similar) and the neutral wire to the utility AND the earthing wire are both loose at the same time, the voltage may become higher than normal (or lower than normal).
High voltage is usually first noticed as failing incandescent bulbs. Low voltage is usually first noticed as dim or flickering incandescent lights or slower than normal fans.
Florescent lights and appliances are not noticeable affected until the voltage gets down into the 90s volt range.
Shocks from electrical devices or in tubs and showers can also occur.
If you think this is what's happening, have the utility check its connections and have the electrician check the main earthing in the building.
Working on this without the right training can be.. well... shocking!!

Answer 3

The most likely cause is a voltage problem. Your solution is that electrician you are waiting for. Improper wiring could be the problem. It is unlikely no ground in one fixture could cause voltage problems in another, but if one was wired poorly so could the other. You might visually check the fixture that is blowing bulbs. If you know what you are doing, run some voltage checks on fixtures and plugs. There is a tester that just plugs into wall socket that will tell if the wiring is correct. About 10$ at any hardware store.

I have the same problem, my house is a older timber framed home and if we do any hammering or work on the house the light globes blow, perhaps this is what is happening ?
