I tested for several LED lamps, since I am so far always been a little skeptical of LED lamps. After a very fast delivery, the curiosity about the new bulbs was very large. Once the LED's screwed and the lights were turned on, the big surprise came: Everything Great! The lamps provide a very nice, bright light! At the processing there is nothing wrong, and I have to compare it to other manufacturers. I am very happy with the test and will try to gradually all the "old" lamps against these LEDs exchange where they are attached.
