HID ballasts control the voltage and current for high-intensity discharge lamps such as metal halide, high-pressure sodium, and mercury vapor bulbs. These ballasts are crucial for starting the lamp and regulating power during operation, ensuring safe and efficient performance. They are commonly used in stadiums, warehouses, and outdoor lighting systems.
Available in various wattages and input voltages, HID ballasts support long lamp life and consistent brightness in large-scale lighting applications.
