Of course it's possible that it has been lying on my lamps and they do not have tolerated with the LEDs, but after I plugged it, at first I thought I was hallucinating. The whole room was filled with a buzzing sound, as one knows her public "bathrooms". As if one would adjacently on 100 fluorescent lamps. That made me so afraid that I have returned the LEDs immediately what problems walked across the stage. Thanks a lot for this. Nevertheless, these LEDs are probably only suitable for hard of hearing people. Too bad, because the color temperature was not too bad in itself.
