When the lamp with carbonized thread lasted for forty-five hours the staff at Menlo Park  realized that they had had a breakthrough. Edison claimed, "none of us could go to bed,  and there was no sleep for any of us for forty hours." In November 1879 they tried using  carbonized cardboard, and soon they had created an experimental bulb that was  superior to any of the others they had tested. On New Year's Eve, the Menlo Park facility was swarmed by the press, on- lookers, and  Edison's financiers, all eager to see the new invention. Edison enthralled the visitors by  lighting forty light bulbs all at once, then switching them on and off. The real work,  however, consisted in creating a system that was inexpensive and practical: true  innovation lay in lighting on a much larger scale, which required generator systems and  safety fuse technology.
