What Watt? is a memorial to the incandescent light bulb. Itís a spherical chandelier made up of 1243 suspended bulbs of various shape and size, illuminated by a single low-energy light source. As all forms of incandescent light are phased out in favour of greener alternatives, What Watt? marks the passing of a design that had remained relatively unchanged since its invention 130 years ago. An edition of ten.
