I had bought two of the lamps. They are (or were ...) about 8 hours a day and were in use in each case once turned on and off during the day. The shifts I have indicated with because the electronics are also a common cause of failure. After 3 weeks, the first lamp turned out in the 4th week the second. Indicated a life expectancy of an average 50,000 hours. I therefore of a misprint (hours rather than minutes) => 50.000 minutes have about 34 days ago. Joking aside: At first I was thinking of a manufacturing defect; but since now both lamps are broken, I conclude that from now. There is seemingly simple Billigkram. I have the house all indoor and outdoor lighting (approximately 130 bulbs of different manufacturers and types) equipped with LEDs with me. Except for the two Lighting EVER there have been no failures. It was my first and probably last attempt with this brand.
