Where were the first electric arc lamps installed?

The first electric arc lamps were installed in Paris, France. This development took place in the early 19th century, particularly around the 1850s. The arc lamp, which produces light by creating an electric arc between two carbon electrodes, was crucial in advancing public lighting technology. Paris, at that time, was a hub of innovation and scientific advancement, making it a fitting place for this groundbreaking installation. The use of electric arc lamps in Paris paved the way for their adoption in other major cities worldwide, significantly influencing urban lighting systems and public safety during nighttime.
