Satco 400W Metal Halide Ballast – 5 Tap ANSI M59
The Satco 400W ballast is designed to operate 400W metal halide lamps with five voltage taps ranging from 120 to 480V, accommodating a variety of wiring configurations. Its probe-start design prioritizes reliable ignition and stable operation in fluctuating line voltage settings. The model includes a dry capacitor and bracket kit for convenient installation in standard HID fixtures. Use in applications requiring robust performance with versatile input options.
Universal M400MLTAC4M – 400W M59 Quad-Tap Ballast
Universal Lighting’s M400MLTAC4M features a magnetic core and coil design for metal halide lamps with a 400-watt rating. It supports M59 ANSI code and four input voltages (120/208/240/277V), offering quad-tap flexibility for different regional electrical systems. The ballast is built to handle typical HID loads with a focus on reliability and easy retrofits in existing fixtures. The rugged construction is suitable for outdoor and industrial lighting projects requiring consistent color and lumen maintenance.
Philips HID Ballast Kit – 400 W
Philips’ 400W HID ballast kit is a comprehensive solution featuring a core-and-coil ballast with a built-in capacitor, mounting bracket, and necessary hardware. It supports 60 Hz operation and multiple lamp inputs, covering 120/208/240/277/480V arrangements. The included bracket and components streamline installation, reducing set-up time in field projects. The kit is designed to meet stringent quality standards for long lamp life and stable ballast performance across varying temperatures.
Universal M400ML5AC4M500K – 400W Magnetic Ballast
Universal Lighting’s M400ML5AC4M500K is a magnetic core-and-coil ballast designed for 400W metal halide lamps, with a dual listing for 120-277V and 480V operation. This model emphasizes high luminous efficiency and compatibility with HID fixtures that demand stable color rendering and lumen output. It’s a practical option for facilities updating older lighting systems to meet energy and maintenance standards without replacing entire fixtures.
Sunlite MH400/U/MOG – 400W Metal Halide Lamp
Sunlite’s 400W MH400/U/MOG ballast is tailored for mogul-base (E39) fixtures, combining a 400W metal halide ballast with a robust 60-480V input range. The M59-anchored system delivers strong lumen output (approximately 36,000 ANSI lumens) with a 4,000K color temperature. The product is well-suited for outdoor floodlights, parking areas, and industrial installations that rely on reliable, high-lumen illumination and compatibility with mogul-based lamps.
Buying Guide: Key Considerations for 400W Metal Halide Ballasts
- Compatibility with lamp type and ANSI code: Ensure the ballast supports the specific 400W metal halide lamp you use (e.g., M59, M57/M107) and matches the fixture’s ANSI requirements to avoid compatibility issues and color shifts.
- Voltage input range and taps: Look for ballasts with multi-tap options (e.g., 120-480V) or quad-tap configurations to fit regional electrical standards and simplify future relocations or retrofits.
- Starting method: Probe-start vs. probe-start with capacitors. Probe-start configurations generally offer reliable ignition in varying temperatures, while capacitors can affect inrush and overall efficiency in certain fixtures; verify compatibility with your fixture’s ballast tray.
- Dimensions and mounting: Compare ballast dimensions with your fixture’s space constraints. Some models include mounting brackets and hardware, which can reduce installation time and ensure secure mounting.
- Efficiency and lumen maintenance: 400W metal halide ballasts affect luminous efficacy and color rendering. Choose ballasts that maintain stable lumen output and color over the lamp’s rated life for visual consistency in outdoor and indoor spaces.
- Durability and operating temperature: Many ballasts are rated for elevated temperatures and outdoor exposure. Review temperature ratings to ensure long-term reliability in harsh environments.
- Warranty and serviceability: Consider brands with solid support and longer warranty terms. This reduces downtime and maintenance costs in commercial settings.
- Fixture integration: For retrofit projects, verify that the ballast kit includes all necessary components (capacitor, bracket, hardware) and that your fixture’s ballast tray can accommodate the new ballast’s mounting footprint.
- Energy considerations: While 400W metal halide remains common for high-lumen outdoor lighting, compare ballast efficiency and potential retrofits to newer HID options or LED alternatives when planning a modernization project.
- Spare parts and replacements: Check the availability of compatible replacement lamps and ballast components to minimize maintenance delays and keep systems running smoothly.
All five ballasts listed above are widely used in outdoor and industrial lighting installations. When selecting the best option, prioritize fixture compatibility, voltage requirements, and the availability of installation accessories. A balanced approach, combining reliable ignition, stable lumen output, and practical mounting solutions, will support long-term performance with minimal maintenance.
