The products listed below focus on mercury vapor technology for outdoor street and area lighting, with one LED alternative included for comparison. Each section provides a concise overview, key features, and practical notes to support a shopping decision.
Sunlite 100W MV100/DX/MOG H37 Mercury Vapor Lamp
The Sunlite MV100/DX/MOG is a 100-watt mercury vapor lamp with a Mogul E39 base, designed for outdoor lighting and industrial fixtures. It delivers about 4200 lumens with a color temperature around 3600K, suitable for streetlights, parking lots, and warehouses. The lamp’s coated white glass helps reduce glare and provides long service life with steady lumen maintenance, making it a practical choice for high-traffic exterior applications.
Key considerations: good energy efficiency for HID options, robust for exterior use, and strong lumen output suitable for medium-range street lighting. Its larger Mogul base fits many traditional HID fixtures, but replacement availability and ballast compatibility should be checked with your lighting system.
CORDELIA LIGHTING 175W Mercury Vapor Lightbulb
The CORDELIA LIGHTING 175W MV lamp is intended for outdoor security lighting and other exterior fixtures that require a reliable HID source. At 175 watts, it provides substantial brightness with the classic amber-white tone typical of mercury vapor lighting. Its Mogul base (E39) ensures compatibility with many street and area lighting fixtures, making it a straightforward option for retrofits or upgrades in existing HID installations.
Key considerations: higher wattage than 100W options, strong endurance for security lighting, and compatibility with legacy ballast setups. As with all MV lamps, confirm ballast type and fixture suitability prior to replacement to avoid mismatches or reduced performance.
Sunlite 400W MV400/DX/MOG H37 Mercury Vapor Lamp
The Sunlite MV400/DX/MOG is a high-output 400-watt mercury vapor lamp with an E39 Mogul base. It delivers up to 22,000 lumens at a color temperature of about 3600K, making it suitable for large outdoor areas, parking structures, and industrial yards requiring intense illumination. The long service life and lumen stability are advantages for sites where maintenance visits are infrequent and consistent brightness is essential.
Key considerations: higher ballast loading and heat output require compatible fixtures and cooling. This lamp is best suited for larger outdoor installations or retrofit projects where high photometric performance is needed to cover wide areas. Ensure fixture enclosures and wiring can handle the operating parameters.
Satco S4475 3900K 75-Watt Mercury Vapor Lamp
The Satco S4475 is a 75-watt coated medium-base ED17 mercury vapor lamp rated for exterior use. It offers a 3900K color temperature, typical for outdoor lighting applications that require a blend of good color rendering and efficient brightness. The ED17 base makes it compatible with many smaller outdoor fixtures, including wall packs and certain canopy lights, where lower-wattage MV options are appropriate.
Key considerations: smaller form factor and wattage can be advantageous for retrofits in constrained fixtures. Confirm ballast compatibility and the fixture’s ability to support MV technology at this wattage and color temperature to maintain proper performance and life expectancy.
GTAREN 50W Corn LED Light Bulb (LED Alternative)
The GTAREN 50W Corn LED Light Bulb is included as an LED alternative for outdoor lighting. It provides an energy-efficient option with up to 6500 lumens and 5000K daylight color temperature. These bulbs are designed for retrofit in E26/E39 bases and eliminate ballast requirements, delivering instant-on brightness with long life expectancy. While not a mercury vapor lamp, LEDs offer immediate energy savings and reduced maintenance for outdoor lighting in appropriate fixtures.
Key considerations: LED corn bulbs require compatible fixtures and drivers, and many installations will need ballast-free operation. For sites historically using MV, this option can represent a modern upgrade path when ballast compatibility is addressed and fixture housings are appropriate for LED heat dissipation.
Buying Guide: Key considerations for mercury vapor street lights
- Fixture compatibility: Mercury vapor lamps require compatible ballasts and fixtures engineered for HID operation. Confirm base type (often Mogul E39) and ballast compatibility before purchasing replacements.
- Wattage and lumen output: MV lamps range from 75W to 400W and beyond, with lumen outputs spanning from thousands to tens of thousands. Choose a wattage that matches the area’s lighting needs and uniformity goals.
- Color temperature and rendering: MV lamps typically run around 3600K with decent color rendering, which affects visibility and perceived safety. If precise color accuracy is important, compare CRI ratings and color consistency across brands.
- Life and maintenance: MV lamps offer long service life but may require periodic ballast checks and fixture maintenance. Consider expected maintenance windows and accessibility when planning upgrades.
- Energy considerations: HID systems consume more energy than LEDs, but MV lamps provide robust performance for certain installations. In new builds, assess whether LED retrofits or MV replacements provide the best long-term return on investment.
- Environmental and regulatory factors: Some municipalities and facilities prefer ballast-friendly retrofits due to historical infrastructure. Ensure compliance with local codes and utility incentives when upgrading outdoor lighting.
- LED alternatives: For projects open to modernization, LEDs can simplify installation (no ballast) and reduce maintenance. Compare lifetime costs, lumen maintenance, and color consistency when evaluating MV vs LED options for street lighting.
Overall, mercury vapor street lights deliver reliable outdoor illumination with established performance characteristics. The five products highlighted provide a mix of wattage, base types, and configurations to fit common exterior lighting scenarios, from mid-range street lighting to high-output yard applications. The buying guide emphasizes practical factors to ensure a well-informed choice aligned with fixture compatibility, energy considerations, and long-term maintenance.
