this LED solar wall lamps, the light provides for reliable, where it is needed. Practically, it is of course in the entrance area, but also very skilled on the terrace, as well as the garden shed or garage. The motion sensor works just fine and should the 30 second time is too short, a sufficient hint and the lights go on. The brightness is more than adequate for my needs, both in terms of brightness per se, and in terms of duration. He really turns on even in the early morning, when it was claimed that all night. The design is simple, more elegant and not too bulky as some other parts that not even brighter. The only drawback in my copy is that he no longer wants to go out even on the first evening turning easy. I suspect, however, that I've got probably caught a radiator with defect. Remedy creates a short exposure to light then uses the normal 30 seconds operation at the next movement. In this respect, a real power switch is certainly desirable. Under safety aspects, however, you should really have time uninvited guests, it is more advantageous that you can stand only with the pricker in a not so quickly visible hole in order to paralyze the good piece. The price-performance ratio is consistent, without the defect, I would mount the device at any time.
