The hand-bent steel substructure of the sculpture is covered in a skin of incandescent light bulbs (new and burnt out), and rear-lit from within by 250 compact fluorescent bulbs, pulling a total power of approximately 20 amps (the equivalent of two household outlets  ).Each of these bulbs is attached to a pull-string, allowing viewers to control the illumination of the structure – like lightning in the CLOUD above them.

왕 유양
artificial moon
Artificial Moon is a sculptural piece by Beijing-based artist Wang Yuyang constructed from hundreds of various compact fluorescent lightbulbs. At over 13 ft. wide (400cm) the piece is an imposing recreation of Earth’s moon, using strategically placed lights to mimic craters and other surface features. Its creation is also particularly poignant, as it was originally put on exhibit in Shanghai, a city that due to light pollution is often unable witness the actual moon moving through the night sky.
