Lamp is working properly

The second lamp of this kind that we have now bought a result of positive experiences with the first, although not dependent, but the first is for it after 2 months of operation still tiptop. Only the brightness sensor, we had to readjust, there seasonally, different light is out and this led daytime Selbstanschaltung to the lamp, which we had not intended.
Because many buyers had pointed pointing out the low water tolerance of the sensor, we have assembled a plate over the lamp to shield the rain.
