50k hours is probably ambitious for some, but not too far off the mark. The Achilles' heel here is the capacitors, they are the weakest link. 10k hours is easy, and they should never fail before that absent some design or manufacturer defect, or atypically high ambient temperatures. >I've had several expensive (Phillips/GE) LED bulbs fail after a year of sparse usage. You have an electrical problem in your home. Perhaps a poor connection on the neutral leg of the circuit. It is even potentially unsafe, as in a possible arcing condition.

When we moved in two years ago there was an intermittent earth fault, so we had everything checked then. They found the earth fault, it was a loose connector inside a T junction I believe. I'm more inclined to believe it is caused by the crappy wiring system that is standard in my country, where there is not a neutral lead and a live one, but two live ones with a phase shift.

If there was one, there may be others. I've located several loose junctions in my attic (on my bathroom electric strip heaters). They were easy to spot because of the discolored insulation. At my own home my connection to the electrical grid also had such a fault (a corroded junction on one phase). It was an intermittent but persistent fault and I am surprised that I didn't ruin more electrical stuff before I found it. >I'm more inclined to believe it is caused by the crappy wiring system that is standard in my country, where there is not a neutral lead and a live one, but two live ones with a phase shift. Sorry, I shouldn't have assumed you were in North America.
