Incredible scrap! 0 stars

That's the second motion and make as this which gives up the ghost.
The 1st held a day until the lamp just stayed on.
OK, now I had drilled the hole in the ceiling, so ordered another and installed.
Has exactly two hours to work, then there was a bang and flash of light.
Since I am an electronics I have ever looked into it, the cause of the failure is a false misplaced ribbon cable leading to close to a 230V conductor.
So I'm going but get a high quality sensor, I've had enough!
