Might’ve gotten a bad batch. I know a local business that had to replace tons of them in new houses because a specific manufacturer had issues with one of their production runs and they would go out/or flicker non-stop within the first few years at random. Replaced about 15 of them in my own house within the first few years of a new build. “Luckily” lightning struck the house and insurance paid to replace them all with another brand and no more flickering led’s now.
