Nieuwenborg and Wegman Tetrahedron floor lamp Indoor Netherlands 1979

Sculptural Tetrahedron floor lamp designed by Frans van Nieuwenborg and Martijn Wegman and manufactured by Indoor in the Netherlands in 1979, featuring an extraordinary geometric construction that beautifully combines glass, metal and light. The striking triangular structure is formed by transparent glass panels, connected by black corner fittings. Its minimalist design creates a fascinating interplay of transparency, reflections and geometric lines, giving the lamp an almost architectural appearance. At the centre of the construction, a single exposed light bulb is suspended within a smaller triangular metal framework. When illuminated, the light reflects through the surrounding glass surfaces, creating an intriguing visual effect while emphasizing the lamp's unique three-dimensional form. The lamp is marked on the glass, confirming its origin and authenticity. Its impressive proportions and transparent construction make it a remarkable statement piece without visually dominating the surrounding space. A wonderful example of experimental Dutch design from the late 1970s, combining geometric precision, innovative materials and sculptural elegance. A true conversation piece that functions equally well as lighting and as a work of art.
