The "triuna" pendant lamp is a design inspired by the costumes of the "triadisches ballett" by oskar schlemmer and the ideas of the bauhaus school. The combination of simple, geometric shapes and noble materials such as brass and glass creates a harmonious whole. In the "triadisches ballett", three female dancers and three male dancers represent three categories of human existence: human, machine, and nature. In the "triuna" lamp design, three brass rods symbolize these three categories, creating a symbolic triangle. the brass bars with brushed and waxed finish can be replaced with bars made of oxidized steel. The lamp has a white textile cable. the lampshade is made of matte opal glass that perfectly disperses light, creating a pleasant and harmonious atmosphere. The lampshade is open at the bottom, allowing for partially direct lighting of a chosen surface. the lamp works with a standard 1 x e26/e27 bulb. It is recommended to use a maximum of 60w standard bulb or led bulb without watt limits. The cord can be easily shortened and adjusted at the ceiling canopy.
