The lamp is intelligently contoured with plenty of space for connecting parts (wires) which greatly facilitates the installation. The downward motion sensor comes my special requirements which are contrary: The lamp will only light up when people in front or through a door, on which the lamp is mounted, move. Thus, the sensor is not in motion, etc. of plants light, through which runs the wind. The severely restrict the scattering effect of the sensor and can be focused in a targeted, this is ideal achieved. After several attempts with different bulbs they met for the first time these wishes. Just adds that to me on the lamp by its own ineptitude before assembly of the ladder on the Concrete floor has fallen and the sensor is pressed. However, this has the function of the lamp in any way impaired. This in turn made me very surprised. I can only recommend the lamp.
