One after the other

1 year ago I bought those 6 LED bulbs with great hope. The first negative impression was the light intensity indicated, perhaps only 50% of the declared value. Now after 1 year they already slow burning all through. From 6 have 3 given up the ghost, and really did not do a "euthanasia". Every day, they were really only by the hour in use. UFO I'm not, so of 50,000 hours (or even 25000 hours) away. Too bad but I would advise against it, unfortunately, all to buy such LED lamps. I know it did not know if I can send them back to Amazon.
