For the optics, the mounted shock-proof plug and the LED I give five stars. Unfortunately I have to pull the mounting bracket a star. The M8 was unclean and had to be recut. The screws could be difficult to unscrew. They also have an unusual for us wrench size of 14mm. (Normally 13mm) In the hope that not all the floodlights have this little defect, I will give a clear decision to buy!
