Amazon Basics bulbs possible diode failure after only one year

I've got a handful of Amazon Basics builds in my house, most frequently set to Cool White at 100% brightness. I've had them for only a year, probably closer to 9 months really, and one of them a month or two ago started failing after only a minute when set to Cool white and similar hues, and after only a day or so of that it would only stay lit when at to a red hue. And now that's started happening with a second bulb. it doesn't appear to be a wifi issue as the other bulbs and other devices on that wifi have no problems, and while I haven't started troubleshooting the second failed bulb, the first one wasn't fixed by the usual power cycling or even removing it from Alexa and re-pairing it. A new bulb in that same socket works fine. It seems like a diode failure, and those two bulbs are from the same box of four, but it's way too soon to be having a diode failure, isn't it? Any thoughts from those more experienced and knowledgeable than I am? Were these possibly bad bulbs, or could the sockets be draining their lifespan faster than usual? Or is this a known problem with Amazon Basics builds and a more expensive option like Philips be the better investment?

Sorry for the wall of text. TL,DR: Amazon bulbs seem to possibly have a diode failure after less than a year. Thoughts?
