Inspired by a blooming sunflower, this high bay lighting features an unusual design idiom. It is not only suitable for the use in industrial environments but also in gastronomy and cultural facilities. The design is based on the chimney effect in the heat dissipation principle: the hollow in the central part as well as several recesses enable a quick heat exchange. The use of high-performance LED chips, equipped with robust 3D lenses, yield precise, energy-efficient light distribution.
