Advance 71A5570-001D – 150/175 Watt Ballast
The Advance 71A5570-001D ballast handles both 150W M107 and 175W M57 metal halide lamps, with versatility across multiple voltages: 120/208/240/277V. Includes a dry capacitor and bracket kit for straightforward mounting. This model is suitable for retrofit projects and commercial fixtures requiring dependable startup and steady lumen maintenance over time.
Sunlite MH400/U/MOG 400W MH Lamp
While primarily a lamp rather than a ballast, the Sunlite MH400/U/MOG is a 400W metal halide lamp designed for mogul bases (E39). When paired with a compatible ballast, it provides high lumen output (approximately 36,000 lumens) and a color temperature around 4000K. Ideal for outdoor and large-area commercial applications, it complements ballast systems that support high-wattage HID lighting with robust lumen maintenance.
Sunlite MH250/U/MOG 250W
The Sunlite MH250/U/MOG lamp is a 250W HID bulb designed for mogul bases (E39). It delivers strong efficacy and reliable output when paired with suitable ballasts, making it a practical option for street lighting, parking lot fixtures, and other industrial installations. With a 15,000-hour life and stable color rendering, this lamp supports long service intervals in demanding environments.
Sunlite M102/O Protected MH Lamp
The Sunlite M102/O is a 150W protected metal halide lamp designed to reduce color shifts and improve reliability in outdoor and industrial fixtures. The protected design enhances lamp life by mitigating arc tube damage in challenging environments. Use this lamp with a compatible ballast to achieve consistent light output and extended service life in street and area lighting applications.
Buying Guide: Key Considerations When Choosing a Ballast
- Wattage and lamp compatibility: Ensure the ballast supports the exact wattage and lamp type (M57, M107, or E39 mogul) required by your fixture. Mismatches can reduce efficiency and shorten lamp life.
- Voltage range and input options: Look for ballasts that support the fixture’s supply voltage (120V, 208V, 240V, 277V, etc.) to ensure reliable startup and operation across installations.
- Electronic vs magnetic: Electronic ballasts offer improved energy efficiency, shorter startup times, and reduced flicker, while magnetic ballasts are often simpler and more rugged. Consider environmental conditions and maintenance plans when choosing.
- Starting and lumen maintenance: High-quality ballasts provide stable starting performance and minimize lumen depreciation over time, preserving light output for longer periods.
- Size, mounting, and installation: Check bracket kits, dry capacitors, and mounting hardware included with the ballast. Proper installation supports safer operation and easier maintenance.
- Durability and IP rating: For outdoor and industrial environments, select ballasts with appropriate weather resistance and enclosure protection to withstand dust and moisture.
- Compliance and compatibility: Ensure the ballast complies with local electrical codes and is compatible with your existing fixtures, reflectors, and wiring configurations.
In selecting a ballast for metal halide lamps, prioritize compatibility with lamp wattage and base type, voltage flexibility, and the expected operating environment. The products listed above offer a range of options for common MH applications, from compact 39W systems to higher-wattage 250–400W setups. For horticultural or architectural applications, consider ballasts that support precise control and steady output to maximize lumen maintenance and color rendering over time.
