I do not know where you could the Lunartec Solar "cobblestone" install, outdoors, anyway. Have a total of 8 "stones" used in my paved driveway as boundary mark this spring. After admittedly several rainy days (remember spring 2013 !!!) are all "stones" centimeters tall flooded with water, ie all electrical parts and cables inside the stone are underwater. The truly wondrous about this product is that it nevertheless still works. But if I look at the corroded cable connections, it's probably only a matter of time until all eight "bricks" give up the ghost. Those things are simply not dense and run completely full of water. Unsightly side effect: the water inlet corrode the maintenance achievements of LED lamps and coat these with a rotgelblichen rust fluid. About the stability of the "stones" per se, I do not want to leave me closer, but it is probably not constitute a supply of several "stones" (made of polyresin, whatever that is) giving, in the not at least one of the "stones" crumbles when receiver arrives. The price of solar paving "stone" could have come on it that this is not necessarily a high-quality product .... In any case, stay away if you want to expose the things of the weather. They would eventually buy no goggles without glasses.
