I am buying philips now when I have to replace them, so far, only 1 philips led died. So they are much more durable, but still not living to the promise of "change once and it will last forever".
I also suspect that many LEDs are designed for 220V, but here in switzerland it is 240V norm and in the middle of the day my power meter reads around 245V (I suspect it is because there is a lot of solar panels on the roofs around me), so it is not a negligible voltage difference if the electronic is not designed for it.
