Outdoor wall lamp Mast Twin made of concrete and brass - seawater resistant The visible parts of the outdoor wall light Mast Twin are made of concrete. The use of solid brass for the metal components makes the luminaire seawater-resistant and therefore also mountable on buildings in coastal regions. A user-friendly plug-in terminal connection allows for easy, tool-free installation with loop-in loop-out wiring. The outdoor wall luminaire Mast Twin is equipped with a central cable entry and emits its light downwards, making it ideal for lighting in the entrance area or on the terrace. LED bulbs up to 6W can be used in the GU10 sockets, making lighting with the Mast Twin outdoor wall light energy efficient and contemporary.
