GROOVE is an innovative outdoor/indoor in-ground recessed system for direct view light—ideal for contour and path illumination in large urban areas, malls, and pedestrian zones. Like the thread of Ariadne guides Teseo through the labyrinth to escape the Minotaur, the GROOVE lighting system points the way through architectural volumes. Given the distinctive light effect, this unique drive-over ground-recessed modular system allows designers and architects to vamp up unique ideas to be used in projects with all the necessary freedom. GROOVE 21 builds in new and sophisticated technological processes: a double layer of transparent resin to guarantee IP rating and reliable performance even in extreme conditions, an additional layer of opal resin to guarantee uniform light.
