Poetic expression of craft, light, technology and mood. Integration of the light and material and making it pass through in such a way that it becomes invisible and then appears out of nowhere.

With Guise Stefan Diez has discovered a new potential use for LED technology in contact with matter: The light emanates from the piece of glass, while the source remains invisible. With this approach Guise achieves a magical effect and at the same time is fully functional. Because of the transparency of the glass when switched off the lamp almost disappears. When switched on it expresses a luminous and almost magnetic presence.
The wall sconce version with a different formal expression features a glass disk that gives off a perimeter glow where the Led light source is also hidden. When turned off it becomes fused with its background, when on it evokes a solar eclipse. 

The glass of the difusor is made of borosilicate. It is typical for the glass to have small air bubbles, some inclusions and tiny scratches. These do not affect the quality or the resistance of the glass.

Stefan Diez

Growing up in a household of 4th-generation carpenters, Stefan Diez’s early bond with craftsmanship has profoundly shaped his development as an industrial designer. Following his family tradition by training as a cabinetmaker, he went on to study industrial design under Richard Sapper at the State Academy of Fine Arts Stuttgart. After returning to Munich to work with Konstantin Grcic, he founded his own studio in 2002.

From 2007 to 2014, he was professor of industrial design at the University of Arts and Design Karlsruhe (HFG), before joining the School of Industrial Design Lund, Sweden, in 2015.

In 2008, Stefan Diez established his studio in the renovated facilities of a former joinery, which provides the ideal platform for his unique combination of hands-on experimentation and technical know-how. Led by curiosity and supported by a network of local craftsmen and specialists, DIEZ OFFICE is dedicated to transforming ideas into actual products with great diligence and proficiency.

Together with his team, Stefan Diez has been exploring a broad spectrum of design, creating award-winning furniture, tableware and accessories, in collaboration with internationally renowned manufacturers like e15, emu, Hay, Rosenthal, Thonet, Vibia, Wagner and Wilkhahn.

Light creates, renders and gives life. Through light we perceive the landscape, architecture and the spaces we inhabit, stimulating our senses and perceptions. Each of us possesses a unique identity, a personal point of view and a subjective way of perceiving reality.
