quite petite, but Very luminous and very functional radiators. Very easy installation, as always, the screws are, however, more difficult to use, since settled at the high end of the scale, which makes known but unfortunately in most cases on the included mounting hardware. Clamping is simple. The settings for the burn time and the light sensitivity of the motion appear rather fiddly, they should be granted not for too long service life with frequent and somewhat rougher Use the adjustment screws. The three-dimensional adjustment of the radiator is quite limited, it can always be on a vertical axis away from one another and converge on a horizontal axis and up and swing down, not turn for example via a ball joint. Otherwise, good value for money, strong light output with small 4W consumption per lamp, easy installation. Recommended Overall
