Object Details
- Edison, Thomas Alva
- Description
- On December 31, 1879, Thomas Edison invited the world to his Menlo Park laboratory for a demonstration of his new lighting system. He and his team lighted the laboratory, the office, the grounds, and the boarding house across the street with about 100 incandescent lamps. This is one of the lamps from that demonstration. Fitted with a filament made of Bristol-board, the lamp could operate for about 125 hours, long enough for a demonstration but not for a commercial product. Edison’s began selling an improved lamp in early 1880 that used a bamboo filament and operated for about 600 hours.
