Variable modular lighting system

A device comprising:

• a hollow box, wherein the box comprises:
• a central rectangular cuboid comprising a first edge, second edge and a third edge, where the first, second and third edges are perpendicular and meet at a first vertex and so define the cuboid in three dimensions, the central rectangular cuboid further comprising a fourth edge and a fifth edge, where the second edge and the fourth edge and the fifth edge are perpendicular and meet at a second vertex and the first edge and the fourth edge are parallel and approximately equal in length and the third edge and fifth edge are parallel and approximately equal in length, and the central rectangular cuboid further comprising four faces, where the first, second and fourth edge define the first face and the second, third and fifth edges define the second face;
• and the first and third edges do not define a face and the fourth and fifth edges do not define a face;
• and
• two opposed irregular triangular prism-shaped wings with a first irregular triangular prism-shaped wing attached to the first edge and the third edge of the central rectangular cuboid and having a sixth edge not attached to the central rectangular cuboid and defining the peak of the first irregular triangle;
• and a second irregular triangular prism-shaped wing attached to the fourth edge and fifth edge of the central rectangular cuboid, and having a seventh edge not attached to the central rectangular cuboid and defining the peak of the second irregular triangle.
