The research of pure light is like the North Star for those who dedicate themselves to the design of fittings for architectural lighting. The light creates, emphasizes and underlines the architectonic details, while the material shapes are often a superfluous and intrusive element. This is why ARCLUCE designed KRIO, a full-light walk-over recessed fixture for high or low intensity LED only. This innovative concept of lighting allows the installation of several fittings in continuous lines, in order to create uninterrupted light routes of variable length on the ground or into the wall. Its thin and net line makes KRIO particularly fit to highlight and point out paths; moreover, it can be installed in front of walls to obtain a wall-washer light effect. The RGB LED chromatic qualities allow to combine the colours suitable to each different environment. Thanks to its high IP67 protection degree, KRIO is also perfect for outdoor applications.
