Arc lamps are 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 particularly useful for outdoor lighting, searchlights, and large venues. They are known for their high intensity and efficiency compared to traditional incandescent bulbs. The design of arc lamps typically includes a glass enclosure filled with gas, which helps sustain the arc. Common gases used include argon or neon. While they have been largely replaced by more modern lighting technologies like LEDs, arc lamps are still appreciated for their unique brightness and historical significance in the development of electric lighting.
