Who - is to illuminate not just a driveway or garden, for this minimum solution is thoroughly recommended - only a balcony as in my case. The installation using the enclosed dowels and screws is not an act for the untrained opportunity craftsmen. The motion registered quickly once the balcony is accessed. The lights turn off after about 30 seconds off automatically. And the fear that every vorbeisummende lighting activated, has so far not materialized. Conclusion: Highly recommended.
