A xenon lamp is a type of gas discharge lamp that produces light by passing an electric current through xenon gas. When the gas is ionized, it emits a bright, white light, making it ideal for applications like automotive headlights and movie projectors. These lamps are known for their high intensity and color temperature, which closely resembles natural daylight. Xenon lamps are often used in situations where high brightness is required, such as in photography and theatrical lighting. They have a longer lifespan compared to traditional incandescent bulbs and are more energy-efficient, although they can be more expensive to produce and operate.
