Industrial Performance HR250DX/TU — 1 Pack
The 1-pack Industrial Performance HR250DX/TU uses an E39 mogul base and is designed for HID fixtures with H37 ballast codes. This 250 W mercury vapor bulb provides reliable, steady illumination suitable for outdoor and industrial environments where long life and consistent color rendering are important. The H37 ballast code indicates compatibility with common HID ballast configurations used in street and area lighting. Installation considerations include ensuring ballast compatibility and matching fixture rating to maintain optimal performance.
Industrial Performance HR250DX/TU — 4 Pack
This four-pack option provides the same 250 W mercury vapor bulbs with E39 mogul bases. The four-pack setup is useful for fleet maintenance or multiple fixtures requiring synchronized replacements. As with single bulbs, confirm ballast compatibility (H37) and ensure proper handling for HID bulbs during installation. Short-term replacement intervals and typical end-of-life behavior should be planned around fixture cycles in outdoor installations.
GE Lighting 32127 250W Mercury Vapor Bulb
GE’s 32127 250W mercury vapor bulb emphasizes reliability and compatibility with standard mogul-base HID luminaires. Designed for easy integration, this bulb is often chosen for outdoor lighting due to its robust construction and broad availability. While GE notes simple operation and durability, users should verify that the ballast and fixture are suitable for mercury vapor technology and that color rendering aligns with application needs, such as area illumination versus accent lighting.
GRUOTVSZAK LU250/MOG 250W HID Bulb
The GRUOTVSZAK LU250/MOG 250W bulb delivers 30,000 lumens with a long life profile over 24,000 hours, making it suitable for high-lumen outdoor applications. The ANSI S50 compatibility with mogul base E39 supports a wide range of fixtures often used in street lighting and parking facilities. Users should ensure ballast compatibility, color temperature expectations (2100K range typical for this class), and precise fixture sizing to avoid over- or under-illumination.
Sunlite 250W — LU250/MOG Bulb
The Sunlite 250W high-pressure sodium bulb listed here overlaps with mercury vapor lighting in some fixture contexts, but its primary technology is HID with a similar mogul base (E39) and applications in outdoor and industrial lighting. This model provides around 28,000 lumens with a 2100K color profile in clear glass. While primarily a sodium lamp, it is often considered in the same category for planning outdoor lighting upgrades, especially where ballast and fixture compatibility are aligned with HID standards.
Industrial Performance — Replacement for GE HR250DX37/40
This replacement bulb from Industrial Performance is designed for GE HR250DX37/40 installations, offering 250 W with frosted glass. It supports an ED28/E39 mogul base configuration to fit a range of legacy HID fixtures. Expect color temperature around 3900K and compatibility with standard ballast types. When replacing, verify fixture tolerance for frosted bulbs and confirm ballast compatibility to maintain consistent light output and color rendering.
Industrial Performance Replacement — Frosted Glass
Note: This entry reiterates a replacement option with frosted glass, indicating a slightly different light transmission profile and potential variations in glare and efficiency. Frosted bulbs can reduce hot spots and improve diffusion in certain fixtures. Confirm ballast compatibility and ensure that the application benefits from the lower glare ordiffused distribution provided by frosted designs.
Buying Guide
- Fixture and ballast compatibility: Ensure the ballast code (e.g., H37, ANSI S50) and mogul base (E39) match your fixture requirements. Mismatches can reduce light output or shorten bulb life.
- Color temperature and optics: Mercury vapor bulbs in this class typically offer around 2100K to 3900K ranges. Choose a color temperature that aligns with task lighting, safety visibility, and the surrounding environment.
- Lumens and efficiency: Higher lumens indicate brighter outdoor illumination. Compare lumens alongside lamp life to estimate total cost of ownership and maintenance intervals.
- Bulb life and maintenance: Look for bulbs with longer total life times (over 20,000 hours) to minimize frequent replacements in hard-to-reach installations.
- Base and form factor: Mogul bases (E39) are common for area lighting. Ensure physical dimensions fit the fixture’s lampholder and cover. Frosted versus clear glass affects glare and diffusion.
- Replacement strategy: For multi-fixture installations, consider buying in packs to simplify inventory and reduce downtime during maintenance.
- Safety and handling: Mercury vapor bulbs contain hazardous materials. Handle with care, dispose of according to local regulations, and avoid breaking bulbs during installation or replacement.
- Application context: Outdoor and industrial sites benefit from high-lumen, durable bulbs. For architectural or security lighting, balance color rendering with energy needs and fixture efficiency.
