Here is another amazing “green” design lamp that piqued my interest.  Luca Casarotta of Cosca Design constructed this transforming lamp out of recycled polyethylene.  In open mode, the Penta lamp can illuminate an entire room.  And when closed, it becomes an orb that doubles as a spotlight.

Make the leap to see the Penta lamp in all modes.
