I wanted to buy an outside light with PIR. I looked at the different products for some time, then managed to pick up one without a PIR and paid for it. Realised my mistake when I arrived home. Back at store I was given my refund and then bought a £19 light with PIR. Spent 2 hours fitting up. The adjusters are not very good. I could not get the light to stay on for less than 5 minutes. However, it would switch off after 5 mins. Came down at 5am and the light was on. I thought it would switch off soon but no, it was still shining away at 6am. I did a manual swith-off. The light is very good but the electronics must be very, very poor quality. I will use ebay next time.
