Flicker and too fast break

Had this bulb bought about a year ago and used without dimmer. Color and brightness I liked. As long as you can turned it was also great. But if they are off by a few hours and then again, it does not turn you on but in an unbearable Flimmerzustand. This remains so until she left for relaxation times an hour or so again. Now after about 1500 hours they gave a crack of itself and now goes no longer. I guess broken electronics. That's just not at all an indication of the service life of 25000hrs + and the price. Perhaps an individual case, but the bulb now heads into the proper disposal and unfortunately I have to advise against it :(
