LED Wall Sconce by ET2 in Black from the Penrose collection.

A cubist work of art, the Penrose collection carefully calculates the structural form of a cube space when corners do not meet. This tracery of this shape is emphasized by its dedicated LED light source housed within aluminum channels and then cast in various directions. Available in Matte Black or Gold, this series is a feat of human engineering in design. Translating a mathematical challenge into a sculptural work of art with the function of delivering light to interior spaces.
