Yeah, I have so many LED bulbs that are rated at "10+ years". I put all of the lights in my apartment 5 years ago. I'd say the failure rate is 10-20% at this point. The particularly painful one is the downlights under my kitchen cabinets. They require removing the entire probably 30 kg board that I have them mounted in, which requires clamping things up and undoing 6 heavy duty screws, and the whole process of changing one takes about an hour. 2 of the 5 have failed in 5 years. I'm very picky about lighting (only get LEDs with CRI 95+), so I usually am buying the expensive ones.

Same here. We have had outdoor hanging string lights for ~10 years with nice incandescent bulbs that occasionally burn out. I thought I would join the 21st century and started replacing the burned out ones with LED versions. Big mistake. In about 3 years, half of the new LED ones have already failed. Managed to find a new pack of the incandescent ones and so far so good.
