In the hallway and bathroom this useful plug-light makes super good service. I have no great lighting at night on the way to enable the bathroom and will therefore also not "awake" before I'm back in bed. Prerequisite for use is only one outlet. It is also good that the sensor can tackle only when it is dark, the lamp in the socket. Once it becomes light in the hallway and bathroom, the plug lamp switches itself off. Unfortunately, the crown could be in one of the 4 lamps do not rotate in the other 3 lights you can choose the angle of illumination itself.
