I have a bought at the same time this product and Osram. By operating with batteries to use in every corner is possible. The power consumption is minimal in this device. The comparative product from Osram is weakening after just one week, so that the luminous efficiency greatly decreases. Also I noticed when Osramprodukt that night often times occurs nuisance tripping and the light comes on, even if there is no motion on the floor. In this product, I can not detect any such nuisance tripping. Although the design may seem a little clunky, Best Buy!
