Long history of incandescent bulbs

The Schenectady Museum and Planetarium displayed a number of old bulbs at GE's lighting symposium yesterday, including these. The bulbs were made from the late 1880s to the early 1900s. On the right in front is a 96-year-old replica of Thomas Edison's first commercial bulb from the 1880s. The fourth bulb from the right in the back row is a gas-filled bulb from 1915, which was inexpensive enough to make electric lighting available to the general public, according to a representative from the museum.
