The 1,000-watt ION® Electronic Ballast A/C works with metal halide and high pressure sodium lamps to achieve superior, long-lasting performance in HID lighting systems. Its microprocessor-driven operation automatically adjusts to a connected lamp's specifications, optimizing lumen output and efficiency over the entire lifespan of the lamp. Variable wattage and Super Charge settings customize output to a wide range of growing applications. For greater reliability in any setup, an integrated fan keeps ballast components running cool while overload protection, staggered ignition, and soft start technology and hot restrike prevention safeguard equipment. Green LEDs indicate operational status. Easy 120-volt/240-volt conversion requires only a swap of power cords (8-foot, 120-volt cord included; 240-volt cord sold separately). This generator-ready ballast is CSA-listed and includes a three-year warranty. Certified FCC-compliant by a USA-based testing facility.
