arc lighting

Arc lighting is a technique that produces bright illumination by creating an electric arc—an intense, continuous electrical discharge—between two electrodes. When a high voltage is applied across these electrodes, a luminous, high-temperature plasma forms, emitting a powerful, white light. Historically used for large-scale lighting such as streets and theaters, arc lamps generate their light through this controlled electrical arc, which provides intense illumination without the need for filaments like in traditional bulbs. The technology relies on precise electrical control to sustain the arc safely and effectively, offering high brightness for specialized lighting applications.
