Advance IMH-70-G-LF Electronic MH Ballast — 70W, 120/277V
Features: Made in Mexico. The unit is designed for a single 70W metal halide lamp and supports 120/277V. Best for compact commercial fixtures requiring dependable 70W HID performance. This ballast is ideal for installations that prioritize straightforward 1-lamp wiring with stable ballast operation. Caution: Installation guidance and local electrical codes should be followed to ensure proper alignment with ballast specifications.
Best for: Small to mid-size commercial spaces, shops, and retrofit projects needing a compact, reliable 70W ballast.
OHLECTRIC Replacement for ICN2P32-SC — 1 & 2 Lamp T8 Fluorescent Ballast
Features: Electronic ballast with 120-277V, instant start, UL listed. Durable materials noted for thermal toughness and stability. Although listed for T8 fluorescent lamps, its robust electronic design offers reliable performance in electronic ballast replacements for multi-lamp HID setups when compatible with system wiring. Caution: Verify lamp type compatibility before replacement, as this unit is primarily designed for fluorescent tubes, not HID metal halide lamps.
Best for: Data centers and facilities upgrading fluorescent ballast systems to modern electronic ballasts, especially where remote wiring and quick-start features are valued.
Hatch MC20-1-F-120X Electronic MH Ballast — 20W
Features: Electronic metal halide ballast, 20W, 120V, 0.2A. Best for small HID fixtures or retrofits requiring tight current control and rapid start. Selected for its compact 20W class, providing efficient operation in small, high-output lighting tasks. Caution: Ensure the ballast supports the 20W HID lamp and the fixture’s electrical configuration to avoid incompatibilities.
Best for: Small storefronts, sign lighting, and compact outdoor fixtures needing a low-wattage MH ballast.
Sunlite MH250/U/MOG M58 Metal Halide Lamp — 250W
Features: 250W HID lamp with Mogul base (E39), ED28, 15,000-hour life, 21,000 lumens, 4000K, clear finish. Best for outdoor or large commercial spaces that require high light output and long service life. This ballast supports large fixtures with high ambient illumination needs. Caution: Larger physically sized units may require dedicated mounting space and proper venting for heat management.
Best for: Street lighting, parking lots, and perimeter lighting where high lumen output is essential.
Sunlite MH400/U/MOG M59 Metal Halide Lamp — 400W
Features: 400W HID lamp with Mogul base (E39), ED37, 12,000-hour life, 36,000 lumens, 4000K, clear finish. Best for high-output outdoor and industrial lighting where intense brightness is required. Choose this if the fixture supports 400W HID lamps and you need broad area coverage. Caution: Ensure power supply capacity and ballast compatibility with 400W lamps and fixture wiring.
Buying Guide
What ballast type matches your lamp and fixture? Electronic ballasts offer smoother starts, higher efficiency, and better power factor for HID systems. Confirm lamp wattage, base type, and voltage (120V, 277V, or multi-volt) before purchase. Consider your environment: outdoor, indoor, or wet locations may require specific enclosure ratings and thermal tolerance. If retrofitting, check compatibility with existing wiring, ballast factor, and ANSI/M98 or M139/M143 designations where applicable.
How to choose by application: residential or small commercial lighting often benefits from 70W or 20W ballasts for compact fixtures. Larger outdoor or industrial fixtures benefit from 250W or 400W ballasts with Mogul bases. For installations requiring fast warm-up and stable dimming, select pulse-start and high power factor models. Always follow local electrical codes during installation.
Installation tips: verify lamp compatibility, use proper wiring diagrams, and ensure secure mounting. If replacing a fluorescent ballast with an HID ballast, do not assume cross-compatibility; verify each component’s electrical characteristics and fixture design.
FAQ
- What is a ballast for metal halide lamps used for? It regulates current to the lamp, provides ignition, and helps maintain stable light output.
- Can I mix ballast brands with my metal halide lamp? Compatibility is not guaranteed; use ballast-lamp pairings recommended by the fixture manufacturer or ballast maker.
- Is an electronic ballast better than a magnetic ballast? Electronic ballasts offer higher efficiency, better power factor, and more consistent light, but magnetic ballasts may be simpler for some older fixtures.
- What should I check before buying a ballast? Lamp wattage, lamp base type, voltage range, and whether the ballast supports the fixture’s duty cycle and ambient conditions.
- Are these ballasts suitable for outdoor use? Some are; verify enclosure rating and environmental specifications for outdoor installations.
- Do these ballasts affect color temperature? The ballast itself generally does not change color temperature; the lamp’s color specification remains the main determinant.
