Cubix brings scalability, volume, and constructive interest to architectural illumination. Arrayed in precisely interconnected relationships, these suspended cubes are joined to each other by a shared leg on each frame. With each cube set at one of four vertical positions to the next, the construction allows for expansive horizontal and vertical arrays across the plane and height of a space. Each cube can support a horizontal LED light-guide or be left as an open frame, providing the flexibility to configure higher or lower density illumination and scale to a variety of spaces. Cubix brings constructivist context to architectural illumination.
