I bought a bunch off Amazon a few years back, I think because the name brand ones were more expensive and possibly also harder to find. Well, pretty much every one of those bulbs has crapped out on me in short order. Many of them after just a few months. I believe the manufacturer has since gone out of business. Anyway, I’ve replaced them all with Philips bulbs and so far not a single one of those has had an issue. Get what you pay for, I guess.
