This is a 100 year light bulb. It was created by Adolphe Chariet, who is known as a rival of inventor Thomas Edison. Carbon was used for the filament, and the light bulb was eight times thicker than the common ones at the time.

This 100-year light bulb was installed in the fire station in Horse Cart House in 1901, survived the renovation in 1937, and came to Fire Station No. 6 in 1976. It was removed for a total of about one week, and has continued to be lit for about 115 years, making it recognized by the Guinness Book of World Records as the world's oldest continuously lit light bulb.
