Addendum: After about 6 hours of standing time, the 2nd bulb failed completely. These return. While some seem lucky, I'm not one of them. I have to say I'm not impressed. I installed one of these in my device, used it for about 6 hours (sometimes it flickered) and I turned it off after use. I turned it on this morning and...nothing. Unscrewed and twisted several times, still does not burn. I replaced it with another one from the pack, the new bulb works but sometimes flickers. Please note that this is a non-dimmable light, so I have no explanation as to why it behaves this way. Sure, it's cheap, but if I can't rely on a lightbulb to do its only job, then what good is it? I'll give it another day, but if the second bulb goes out, they'll come back.
