I bought this Lunartec lamp about 5 months ago. Immediately I noticed the large gap dimensions which are as large at the fixed parts when turning the light that the two plastic parts, which are the lateral anchoring, even when turning fast to disintegrate into two parts. Well, the price was low, the light itself is pleasant. After about 5 months use in the hallway, the light automatically switches on and off again, regardless of whether the sensor can detect any movement. Thus, this lamp is broken after about 5 months.
