I received my light today - It was delivered promply and packed to perfection. No problem so far. I unpacked the light ,followed all the instructions and although a bit fiddly fitted it successfully in an hour or so. The problem came when I tried to adjust the PIR sensor for night time movement only and the light remained on and the sensor adjustment had no effect - I can only conclude the PIR was faulty since the adjustment screw went round and round to no effect. To put it bluntly I was disappointed and brassed off with all the effort I had put in - such is life!!
