Looks good and shines brightly

Now it depends finally - under the balcony - over the terrace. The assembly of the lower part of the lamp is very simple. With two anchors and screws to the ceiling and you're done. A lateral supply of the cable is provided. The assembly of the lamp cover of the lower part is, however, a feat when previously engages the sealing ring between the lower part and the air. But since the whole lamp looks very stable, one must when tightening (approximately 1/10 turn and the lamp cover is firmly) quiet some force. It is important that you have the sensors to adjust the sensitivity of the motion, prior to final assembly of the lamp cover and the sealing ring, on its own matching demand set correctly. Because after mounting the lamp cover with sealing ring on the bottom of the lamp, the cover can even unscrew again with a show of strength. The only problem during installation of the lamp, was the misleading representation to adjust the motion.
A written assembly instructions does not exist, but only a sheet with drawings, from which one has to make its own rhyme. From a manufacturer Osram as I would have expected more. After repeated experimentation's has but then folded up and the lamp fulfills its function. The sensitivity of the motion sensor is so sensitive that with the windows closed and blinds As the lamp when only a tiny gap (1-2 cm) on the roller shutter is open, and you pass behind the window.

Conclusion - for which I now know how to do it, I would buy the lamp again. Because it is a truly beautiful part - and their light is a fuel consumption of just 20 watts, just great.
