Until now, I was disappointed by solar lights because of the lack of luminosity and have therefore not used on my property. Mostly, these lamps were relatively low, which in this lamp is also the case. The delivery except for the lamp, nor the mounting hardware, a user manual and a wrench included. The operating instructions are in German, although not necessarily written by a native German speaker, but understood and adequately. The lamp and processing valuable aspect. Optical certainly the price over accordingly. The application is easy with the supplied materials, the screws of sufficient length. After that, the lamp can be turned on with the wrench. The wrench is a small staff, about as thick as a paper clip, which can be used as well. Requires she is to activate the lying inside on and off switch. So the lamp can only be switched off by people who know the system. The lamp detects whether they should light up or not, what in bright light means that it remains off, saving battery power because of the brightness. The function time is indicated by twelve hours thus perfectly adequate, especially since it starts again after thirty seconds. The light is appropriate for a solar lamp, wherein the difference is still clearly visible to a conventional lamp. The motion sensor responds about 3 4 meters in front of the lamp and is fixed, so for my needs adequately. He reacts quickly and without much delay or failure. The battery is built and a change seems to be not provided. The manufacturer makes no statement to life. The warranty is however twelve months. Conclusion: Cheap solar lamp throws nice light and convinced me.
