Commercial outdoor lights with motion detectors have a me incomprehensible characteristic: they are all ugly. To depose me from the overpriced pabulum (often hailed as "Made in Germany"), I have a bought me "normal" outdoor lamp and pimped with this motion for retrofitting. Well, I could have interpose an external motion detector in the power line, but that was too expensive and would even have been more expensive. So here's the elegant solution: this Lunartec screwed into the lamp socket, bulb over it, set - ready. And it's true: The sensor even passes through frosted glass. And I have not even a half feet from the front door, already jumping on the thing. Coverage as promised 5 meters. If you can live with the fact that the lamp socket by this adapter is now building a little higher, then that is a great alternative. For me not to see him because of the milk glass in the lamp but.
