If one ever needed a demonstration of the power of the compact fluorescent, this is it. Artists/ designers Castor Canadensis (who we have loved previously here, here and here) did this installation at the Gladstone Hotel's Come up to My Room alternative design event this past weekend. They filled wire boxes with dead incandescent bulbs and put one live CFL in the middle of each. They hung them over the entrance, in the trees, inside the hotel. They fed two kilometers of carefully braided cable back to a single outlet in the ceiling of an old hotel. Christina Zeidler completely renovated the joint so thats probably a 20 amp circuit, tops.
Try and get this much light, and this much art, out of one circuit with any other bulb.
