The Sunlite 03610 LU70/MED is a 70-watt high pressure sodium lamp designed for ED17/MED ballast compatibility and a standard E26 base. It delivers approximately 6000 lumens with a warm 2100K color temperature and clear glass for efficient light output. With a long service life, this bulb is suited for street and parking lot fixtures as well as other perimeter lighting applications. The compact bulb measures about 2.16 inches in diameter and 5.38 inches tall, making it a direct replacement in many HID fixtures.
Key features include: high intensity discharge, long operational life, and compatibility with mid-base E26 sockets. It is appropriate for outdoor environments where bright, broad-area illumination is required, and is a practical option for retrofit projects aiming to maximize efficiency without changing ballast configurations.
Satco S3127 2100K 70-Watt Clear Medium Base ED17 Lamp
Satco’s S3127 is a 70-watt ED17 high pressure sodium lamp offering 2100K color temperature in a clear, medium-base bulb. It’s intended for outdoor HID fixtures with ED17/MED bases. While specific lumen and life hours aren’t listed in the provided data, these lamps are commonly chosen for straightforward replacements in street and area lighting where dependable performance is required. Installation involves standard ED17-compatible fixtures, and its compact dimensions align with typical outdoor luminaire designs.
This option emphasizes compatibility and ease of replacement in legacy HID systems. For applications prioritizing a 70W size class with a traditional warm color, the S3127 provides a familiar form factor and ballast compatibility for retrofit projects or ongoing maintenance schedules.
Satco S3129 2100K 150-Watt ED17 Lamp
The Satco S3129 is a higher-wattage ED17 high pressure sodium lamp rated at 150 watts. With a 2100K color temperature, it provides strong, broad area lighting suitable for large outdoor spaces such as parking facilities and perimeter lighting. The bulb features a standard ED17/MED base, aligning with common HID ballast configurations. Dimensions are typically consistent with other ED17 bulbs, ensuring compatibility with most mid-base fixtures. Long life and energy efficiency characteristics are typical strengths of Satco’s HPS line, though specific lumen output and life hours should be confirmed from product datasheets or ballast compatibility guides.
This lamp is a practical choice when higher brightness is required without migrating to new ballast hardware. It supports installations that demand robust illumination and is compatible with ANSI code-based ballast matching when selecting the right fixture.
GRUOTVSZAK LU150/MED High Pressure Sodium Lamp
The GRUOTVSZAK LU150/MED is a high-output 150-watt HPS lamp with 16,200 lumens, designed for ANSI code S55 and a medium base E26. It offers a long service life exceeding 24,000 hours, providing extended usage before replacement. The 2100K color temperature yields a warm, amber glow suitable for street, parking, or perimeter lighting. This bulb’s higher lumen output supports larger outdoor areas or fixtures that require brighter nighttime illumination while maintaining compatible ballast and fixture designs.
When selecting this lamp, verify ballast compatibility with ANSI S55 and ensure the fixture’s housing and socket are rated for ED17/MED bulbs. This option balances high brightness with a durable, long-life profile, suitable for frequent on/off cycling in outdoor environments.

While lower wattage than some peers, this lamp provides efficient outdoor illumination for smaller or medium-sized areas, with a long service life typical of HPS products.
For projects where energy and maintenance costs are a consideration, the LU50/MED offers a balance of brightness and efficiency in a compact form factor. Ensure ballast compatibility and fixture clearance before installation to optimize performance and longevity.
Buying Guide: Key Purchase Considerations
- Ballast compatibility: Verify ANSI codes and ballast type (S62, S55, S68, etc.) to avoid mismatches that can reduce efficiency or shorten bulb life.
- Wattage and lumen balance: Higher wattage yields more lumens but may require larger fixtures and more electricity. Choose wattage that matches the fixture and area size.
- Color temperature: 2100K is common for HPS, delivering a warm amber glow suitable for outdoor security and ambiance. Consider how the color affects visibility and safety.
- Lifespan and maintenance: A longer life reduces maintenance frequency. Look for bulbs advertised with 24,000+ hour lifespans for outdoor deployments.
- Fixture compatibility: Confirm ED17/MED base and fixture dimensions (bulb diameter, height) to ensure proper fit and thermal performance.
- Environmental conditions: Outdoor fixtures face temperature fluctuations. Some bulbs are designed to withstand cycling and weather exposure; verify suitability for your climate.
- Energy impact: While HPS lamps offer good efficiency for outdoor lighting, compare with alternatives (e.g., LED alternatives) if starting a new installation or major retrofit.
- Availability and lead times: Some models may have longer lead times or be subject to supply fluctuations; consider stocking bulbs with compatible ANSI codes.
In summary, the selections above cover a range of wattages and lumen outputs to fit various outdoor lighting needs. From compact 50–70 watt options to higher-output 150 watt lamps, each product supports standard E26 sockets and widely used ANSI ballast configurations, helping to maintain consistent outdoor illumination with reliable service life.
