ypsilon Hannes Wettstein, 1999

Ypsilon is a discrete but energy-saving solution to illuminate the walls of rooms and thus visually enlarge it. The plug-in lamp also solves the problem of dark ceilings where they do not reflect light. Modern electronics and its stylish finishes, along with the distinctive design, ensure high-quality illumination and a long operating life.


The built-in dimmer enables the light to be regulated from bright room light to cozy mood light. Ypsilon is energy saving and can be rotated through 270°. While the natural aluminum and champagne colors contribute to the restrained aesthetics, the red and black models enhance the surroundings and are contrasting points to any interior design.
