Could also be fixture choice. My Feit can lights from Costco have had a couple failures so far, a few years after I bought them, but mostly when I have an LED bulb fail it's been in one of my enclosed fixtures. That's my choice, though, I take the risk. I buy decent quality bulbs, but I like them bright so I end up with 1600 lumen bulbs in an enclosed fixture, which is toasty. They only last a couple years before malfunctioning. Sometimes I can get more time out of them by moving them to table lamps.

I monitor the electric service at my house and it's very steady at 240V.
