Discharge lamps are a type of electric light that produces illumination by passing an electric current through a gas. This process excites the gas molecules, causing them to emit light. Common types of discharge lamps include fluorescent lamps and high-intensity discharge (HID) lamps, which are widely used in homes, offices, and outdoor lighting. These lamps are known for their energy efficiency and long lifespan compared to traditional incandescent bulbs. They come in various colors and intensities, making them suitable for different applications, from street lighting to stage lighting. Discharge lamps are an important part of modern lighting technology.
