But burn the word hits the nail on the head. The sebson G9 LED lamp is poorly processed. From 16 lamps purchased one year gave up 9 pieces. At first I thought to power fluctuations (which was supposed to be no matter LEDs), but then I can adjust it with different lamps at different circuits. A look inside the LED has confirmed my guess. Taking the glass head off (turn courageously, then it breaks) you can see that the solder points partially protrude on the lamps. That is, the fat neatly Lötklecks is loud board next to his destination and probably is much too large, berüht possibly the wrong contact. As a result, the flickering of the Leutkörpers begins with the subsequent total failure. The glass is black at this time, which also indicates a "burnout".
Perhaps there are such and such production lines. This explains why some recessions turn out very well and others do not. For my part, I switched to the MAILUX 2.2 watts G9 LED. Here I've no failure and in terms of size, they fall out even a little less.
