The special feature of the lamp's integrated Bewegungsmelder.Dieser has no way any setting (distance Emfpindlichkeit, burn time). But that can not be faulted because it was not even specified. Worse, he dasss not work reliably. Some of the lamp only switches at a distance But then sometimes turns without triggering on light.
As with so many motion no LED or energy-saving lamps can be used if the wattage of bulbs is too low.
