Daughter has replaced most of the bulbs in their house with LEDs, initially cheap no-name ones from https://cpc.farnell.com/. Many of these are the "candle" style ones in fittings that take 3 bulbs.
We saw a lot of early life failures. Thinking that "you get what you pay for" we've gradually replaced these with Philips equivalents https://cpc.farnell.com/philips-lighting/45479400/lamp-led-candle-nd-5-5-40w-e14/dp/LP10214.
These have been better, but still seeing more early life failures (less than 1 year old) than I'd expect.
I suspect candle style bulbs are less good at dissipating heat than larger bulb styles, but this is still surprising.
I wonder if the mains supply to their house is perhaps over-voltage at times?
I assume there's not much they could do about this, if it's within spec (is that 230v -6% + 10%)?
Presumably all neighbours on the same substation feed would see the same (or similar). Worth getting her to ask around in her street and see if anyone else has experienced the same?
Is it worth getting a data-logger to record the voltage over time, just plugged into a socket, and see if that's a factor?
