I put this light above our front door and it certainly is bright enough to enable me to get the right key in the door lock. The motion sensor works well, lights up when we get close to the door but isn't set off by the cat walking by. I'll be getting a couple more of these for other parts of the garden.
These lights stopped working after about 1 week of outdoor use. Unfortunately I didn't put them outside for 3 weeks after their delivery, so by the time they stopped working the month returns window had expired, so I couldn't return them. If you do buy them make sure you test them immediately. For the week that they worked they weren't too bad, but overall very disappointing.
