How Does HID Lighting Work?
HID, or high definition, lamps are typically required when high levels of light are needed to cover large areas. They are the lights you see at ballgames and theme parks, at stadiums and in gyms. There is a high demand for HID lamps because of their efficiency on a wide scale and their ability to clearly cover huge areas. They come in several versions: mercury vapor lamps, metal halide lamps, and standard high-pressure sodium lights. Mercury vapor lamps were the first commercially available high definition lamps (HID). They are swiftly becoming outdated by newer more efficient counterparts like high-pressure sodium lamps and metal halide lamps. High-pressure sodium lamps generally emit a more yellowish light, but are available with whiter light. They are usually the most efficient, and thus most commonly used, type of HID light. Metal halide lamps produce a beautifully white, natural light, but are also less efficient. How do HID lamps produce light? High intensity discharge lamps prod
