Industrial Performance HR250DX/TU 250W Mercury Vapor Bulb
The 250W mercury vapor HID bulb from Industrial Performance is designed for E39 mogul bases and ballast-coded H37 systems. This option is best for operators who need a straightforward, single-bulb replacement with predictable HID performance. It’s suitable for outdoor lighting, parking areas, and industrial fixtures that rely on a steady, high-intensity discharge light. The unit is described as a 1-Pack with a matching E39 base and ballast compatibility, making it a solid choice for existing HID setups that require minimal modification.
Best for: small to medium facilities upgrading existing 250W mercury vapor fixtures that use H37 ballast codes and E39 sockets. Choose this if you want a direct, simple replacement without changing ballast configuration.
Why selected: Clear compatibility with common H37 ballast codes and a familiar mogul base facilitates faster installation and less downtime.
Caution: Ensure your ballast is listed as H37 and that the fixture’s cordage and socket can support a 250W mercury vapor bulb of this type.
Industrial Performance HR250DX/TU 4 Pack Bulbs
This four-pack provides bulk value for mid-sized installations or maintenance cycles where multiple fixtures share a common 250W mercury vapor bulb. Like the single-pack variant, these bulbs use an E39 mogul base and align with H37 ballast codes. The 4-pack is best for property managers maintaining parking lots, large warehouses, or outdoor fixtures that require consistent lamp replacements at regular intervals. The bulk packaging helps reduce per-lamp downtime and spares crews from frequent reorders.
Best for: operations with multiple HID fixtures or ongoing replacement needs in commercial spaces relying on 250W mercury vapor systems.
Why selected: Bulk packaging lowers maintenance logistics and ensures consistent color and brightness across a fleet of fixtures.
Caution: Verify ballast compatibility for each fixture to avoid mismatches when deploying in a varied array of lighting heads.
Industrial Performance HR250DX/TU 6 Pack Bulbs
The six-pack option is geared toward larger facilities with many HID fixtures, offering a convenient supply of 250W mercury vapor lamps for extended campaigns or seasonal lighting needs. Still using the E39 mogul base and compatible with H37 ballast codes, these bulbs are ideal for parking structures, outdoor walkways, or industrial yards that demand consistent, high-intensity illumination. The bundled option supports efficient maintenance planning and ensures uniform light output across all active fixtures.
Best for: large sites with multiple HID luminaires that require regular bulb changes and uniform brightness across all fixtures.
Why selected: The larger pack reduces downtime and inventory management while keeping performance consistent across the fleet.
Caution: Keep track of batch changes; slight color or brightness variation can occur between lots, so ensure standardization across fixtures when possible.
Replacement for GE HR250WDX37 – Mercury Vapor HID Lamp
This bulb is marketed as a direct replacement for GE HR250WDX37, featuring a 250W mercury vapor HID lamp with an E39 mogul base and ED28 white bulb appearance. The stated length is 8.25 inches, designed for standard HID fixtures. It is best for facilities currently using GE ballast configurations, enabling straightforward retrofits without ballast changes. It provides a familiar 250W HID output suitable for outdoor or industrial spaces that require reliable, high-intensity illumination.
Best for: facilities with GE ballast systems seeking a straightforward drop-in replacement that matches current fixture geometry.
Why selected: Direct compatibility with GE HR250WDX37 minimizes installation time and potential ballast mismatch concerns.
Caution: Confirm that your ballast is compatible with a 250W mercury vapor lamp of this size and that the ED28 white bulb visually matches your fixture requirements.
Sunlite LU250/MOG 250W Mercury/HID (HPS) Lamp
Sunlite’s LU250/MOG is a 250 watt mercury vapor/HID lamp with a mogul base (E39) and ANSI code S50. It’s positioned as a long-life replacement for existing HID fixtures and is commonly used in street lighting, parking lots, and perimeter lighting. The bulb outputs around 28,000 lumens with a color temperature near 2100K, and the clear glass design emphasizes brightness and beam clarity. This option is best for installations requiring a cost-effective bulbed solution with a standard mogul base and reliable performance in outdoor environments.
Best for: outdoor applications like streets or parking areas that benefit from a high-lumen, warm white output with a mogul base.
Why selected: The ANSI code S50 and E39 base support broad compatibility with common outdoor HID fixtures.
Caution: Not all fixtures are designed for the HPS-like color temperature; verify that the fixture’s ballast and lens pairing achieve the desired light appearance.
GRUOTVSZAK LU250/MOG 250W HID Lamp
The GRUOTVSZAK LU250/MOG lamp emphasizes high brightness with up to 30,000 lumens and a long useful life. It uses a mogul base (E39) and is designed to be compatible with ANSI S50 ballasts. The listed life exceeds 24,000 hours, providing durability for long-term outdoor or industrial lighting needs. The clear bulb design supports robust illumination in large open spaces. It’s best for projects requiring high lumen output stored in a reliable 250W HID format.
Best for: projects demanding maximum brightness and extended service life in outdoor or high-traffic areas.
Why selected: High lumen output and long life offer strong value for maintenance-heavy installations.
Caution: Check ballast compatibility and total fixture height, as the 2100K appearance may vary from other 250W mercury vapor bulbs.
Buying Guide: Key Considerations For 250W Mercury Vapor Bulbs
- Base compatibility: Most 250W mercury vapor bulbs use the mogul E39 base. Confirm the fixture socket and ballast are designed for E39 and the H37 ballast code, if specified.
- Ballast match: Mercury vapor lighting requires a ballast code (for example H37) that matches the ballast in your fixture. A mismatch can prevent the lamp from starting or cause unstable operation.
- Lumen output and color: Typical 250W mercury vapor bulbs deliver high lumens with a warm to neutral color. If color consistency matters across multiple fixtures, consider purchasing in larger packs from the same batch.
- Life expectancy and maintenance: Bulbs in the 24,000+ hour range offer longer intervals between replacements. Plan maintenance around fixture access in outdoor or high-traffic areas.
- Age and compatibility with GE or specific fixtures: Some bulbs are marketed as direct GE replacements. Verify that your fixture is compatible with the specific brand and model for reliable performance.
- Installation and handling: Mercury vapor bulbs require careful handling to prevent damage to the bulb envelope. Ensure fixtures have proper enclosure and ventilation as per manufacturer guidelines.
FAQ
- What is a 250W mercury vapor bulb best used for?
Best suited for outdoor lighting, parking lots, streetlights, and large industrial fixtures that need bright, high-intensity discharge light.
- Do 250W mercury vapor bulbs require a specific ballast?
Yes. They typically require a compatible ballast code, such as H37, and a mogul E39 base. Check your fixture’s ballast compatibility before replacement.
- Can I mix brands in a lighting installation?
Mixing brands is possible if all bulbs share the same base, wattage, ballast code, and lumen output. Inconsistent performance may occur if mismatched.
- Are 250W mercury vapor bulbs energy efficient?
Mercury vapor lamps are generally less energy-efficient than newer HID or LED options. They excel in brightness and outdoor visibility but consume more energy per lumen than modern technologies.
- How long do these bulbs typically last?
Expect lifespans up to or beyond 24,000 hours in some models, depending on ballast compatibility and operating conditions.
- What should I do if a bulb doesn’t start?
Check ballast compatibility first. If compatible, inspect the fixture for housing corrosion or wiring faults, and verify bulb seating in the socket is secure.
