Meets high expectations


A modern company needs the right environment for its activities. The WHY system is an indoor pendant luminaire that creates endless arrangement possibilities in office spaces.
The luminaire can shine in four directions – downwards, upwards and sideways. The luminaire can be equipped with an opal diffuser  (WHY1) or a louvre (WHY3). This ensures a very low glare coefficient, which significantly increases working comfort.

Thanks to the unique concave shape and the unprecedented 4-way light distribution, this product creates a new category of 2-in-1 luminaires – where decorative meets functional. The side optics consist of diffusers made of satin PMMA with uniform light distribution, whereas the top features an opal diffuser that ensures the highest efficiency. Two separate circuits for the lighting control of the luminaire's sides and its top an bottom optics give the interior a whole new dimension.
