I've bought several different nameless LED bulbs and gotten poor results, usually not working (dimming or flickering) after a few months. After 6 months these lamps are still as bright and stable as new. Product information is not shown, but they have 3 LED elements at the very end of the lamp, in addition to elements along the length, avoiding a dark area directly on the lamp's axis. In comparison, they are pretty close to an AA battery. They're not as "warm" as I'd like, but they're much better than the "Daytime" versions.
