The small "lock" screw on the Parscan spotlight simultaneously locks both the rotation and the tilt of the luminaire with a single turn. This firstly simplifies the locking of new luminaire positions where luminaires are frequently rearranged and secondly, and especially with wallwashers, it ensures the aim of the luminaire remains unchanged when the lamp is replaced, thus retaining the quality of the lighting concept. This detail fits inconspicuously within the luminaire housing's cantilever bracket.
