An arc lamp is a type of electric light that produces illumination by creating an arc of electricity between two electrodes. This arc generates a bright light, making arc lamps useful in various applications, including street lighting and stage lighting. They are known for their high intensity and efficiency compared to traditional incandescent bulbs. Arc lamps typically use gases, such as argon or neon, to facilitate the electrical discharge. The light produced can be very bright, often requiring special safety measures to protect users from intense glare. These lamps have been largely replaced by more modern lighting technologies, but they are still used in specific settings, such as film projectors and searchlights.
