Voila five months I have this bulb, and although it is too early to talk about reliability in time, I can not and will not wait for two years before mailing me. She really shines well, I think the lumens are just announced. There is no ignition timing, no crackle, nothing that bothers me. It works as it should and I'm happy. This is the price of a low-energy bulb, except that to have spent my entire house with LED, I can only say that the life is not better. No more saving bulbs slamming not even 1 / 5th of the life announced by the manufacturer. Of all the LED bulbs that I have at home (different brands), none asked me problem. So very happy with this purchase.
