Hi, I’ve got a situation where a property keeps blowing bulbs, as in they need to be replaced every couple of weeks. I measure 248v, could that be the problem? Could the problem be external to the property? Apparently the flat above has the same problem.
What possible solution could there be? I’ve thought about installing lights that are 12v, or LED, hoping that the transformers or drivers might deal with the issue. What other options are there?
Thanks
When we moved in here there was a light that needed a new one every couple of weeks. I replaced the socket by a more easy E27 (it was bajonet) and put a LED buld in there. t has been 19 months and it still works like a charm. I did not measure it, I was simply fed up by the bajonet socet and we were changing to LED anyways.
You need to check all the connections in your system, but most likely you will find the problem is a bad connection at the main panel or at the meter since the whole house is affected. Don’t forget to check the system ground too.
A bad connection can spike voltages when it arcs, which can be caused by wire movement, temp or humidity changes, or from conductor heating and cooling as the load varies. Here in the US, older panels by FPE are notorious for self-loosened connections where the power enters from the meter, and the symptoms can be the same as yours is- unexplained voltage spikes and drops. If you’re not up to the task, call an electrician. Better to spend that money now than to spend it for the deductible of your fire insurance policy!

To tell us where you live, makes things a lot easier to answer. Europe is slowly but steady growing towards 230 Volt (244V-207V). Britain comes from the 240 Volt end on the scales, and the mainland comes from the 220 Volt end (242V-198V).
In most cases, the voltage is regulated in the xx,000V/400V transformers. The utility company has to uphold the lowest voltage (between brackets) at the end of the line. Closer to the transformer, the voltage will be higher. Chances are that the starting voltage on a long line (rural area) is on the high side, even in the 240’s. Call your local utility company if this is the case. When I mentioned 400 Volt, I was meaning three fase current of 3 x 230 Volt. In situations where the customers are connected to the grid by wires hanging on poles besides the road, it can happen that two fases connect during a gust of wind. In this case, you get the full 400 Volt blast, during a very brief moment. Once again, call your local utility company. It is also possible that in your house, or in that of your neighbour, there is some (old or faulty) equipment present that causes spikes in the voltage during start-ups. Even a vacuum cleaner of a freezer can be the source. An electronic fuse pops the first time it happens. An oldfashioned (smelting wire) fuse is often too slow to react to one spike, and pops after a number of spikes.
What is your location? I’m guessing you’re not in the US? We run 110v.
This guy is just copy/pasting random post from a forum in the UK:
Yup… He’s another Olight i3s eos Amazon link spammer,this is getting worse.
Sure seemed legit on the surface- thanks for digging up the truth guys. Sure wish we could send a BIG voltage spike to the computer of people like this while they are using it J)

There are a few reasons why lights bulbs blow. The major one is the quality of bulbs you buy. Cheap ones have thinner elements and if there is a power surge, chances are they might blow. Other reasons include: loose connection in the lamp holder or faulty circuits.
From the title of OP’s thread alone, I figured he was mistakenly on the wrong forum posting about some perverse action he enjoyed performing………
“blowing light bulbs”… 
or blowing glass for homebrew bulbs.
