    Electronic Light Ballasts for Tubular Fluorescent Light Bulbs

    Image of Product. Front orientation. Light Ballasts. Electronic Light Ballasts for Tubular Fluorescent Light Bulbs.
    In addition to being more energy-efficient than magnetic ballasts, these electronic ballasts are lighter and quieter. Ballasts that can operate multiple bulbs may have more wires than you need. Cover unused wires with a wire nut.
    Instant Start Ballast—Instant-start ballasts turn on immediately. They are the most energy-efficient, but shorten the bulb's life.

    Light Ballasts for High-Pressure Sodium Light Bulbs

    Image of Product. Front orientation. Light Ballasts. Light Ballasts for High-Pressure Sodium Light Bulbs.
    Magnetic ballasts include a capacitor and starter for a complete high-pressure sodium (HPS) lighting setup. Multi-tap voltage inputs let a single ballast connect to a range of AC supply voltages, simplifying inventory for facilities with mixed electrical infrastructure. Lower-wattage models also accept DC input for off-grid or battery-backed systems. Mounting hardware is included for secure installation in fixture housings or junction boxes.
