After the initial installation, with a show of strength (normal 1.5 cable he could not be connected) was connected, the lamp burned permanently. Before I decided to send the light back, I reread the reviews and found that others had also similar problems. So I opened the lamp again and found that the motion was no electricity - it was namely the brown and the red cable connected. Only after I had the brown cable of the motion detector with phase and the red cable connected to the brown of the lamp, it worked. This must not happen!
