What is another word for carbon arc lamp?
Pronunciation: [kˈɑːbən ˈɑːk lˈamp] (IPA) 
A carbon arc lamp is an early form of electric lamp that uses two carbon electrodes to produce a bright, white light when an electric current is passed between them. Some common synonyms for a carbon arc lamp include arc light, carbon arc torch, carbon arc searchlight, arc lamp, and arc welder. These lamps were widely used in the early 20th century for street lighting, stage lighting, and even in early film projectors. However, they have mostly been replaced by more efficient and longer-lasting electric lighting technologies, such as fluorescent and LED lights. Nevertheless, the carbon arc lamp remains an important part of the history of electric lighting and technology.
