High-Pressure Sodium Lamps (HPS) are a type of gas discharge lamp that produces light by passing an electric current through sodium vapor. They are known for their bright yellow-orange light and high efficiency, making them popular for street lighting and industrial applications. HPS lamps have a long lifespan, typically lasting up to 24,000 hours, and are favored for their ability to illuminate large areas effectively. These lamps operate at high pressure, which allows them to generate more light than traditional incandescent bulbs. HPS lamps are often used in outdoor settings, such as parking lots and highways, due to their ability to penetrate fog and rain. Their energy efficiency contributes to lower electricity costs, making them a practical choice for many lighting needs.
