arc light
Noun: A lamp that produces light when an electric current flows across the gap between two electrodes. This light is created by an electrical arc, which is a continuous, high-intensity discharge of electricity through a gas.
The term "arc light" refers specifically to the lamp or the light source itself. It is often used in historical, technical, or industrial contexts to describe a powerful form of electric lighting. * The early 20th-century factory floor was illuminated by harsh arc lights. * The lighthouse originally used an arc light before switching to newer technology. * The scientist demonstrated how an arc light is generated between two carbon rods.

While "arc light" specifically denotes the lamp, the brilliant, white light it produces is also sometimes colloquially referred to as "arc light." The core meaning remains tied to the source of that light—the electric arc. * The night sky was lit up with the brilliant arc light from the searchlights. (Here, "arc light" refers to the characteristic light produced by such lamps.)
