Sunlite 03610 LU70/MED High Pressure Sodium Light Bulb
The Sunlite 03610 LU70/MED is a high pressure sodium bulb designed for standard ED17/MED shapes with a medium base (E26). It delivers bright illumination, providing up to 6000 lumens at a color temperature of 2100K. With a clear glass bulb and a long life rating of about 24,000 hours, it is well-suited for street lights, parking lots, and perimeter lighting. Its compact dimensions—approximately 2.16 inches in diameter and 5.38 inches tall—make it adaptable to many HID fixtures.
Key features include compatibility with typical HID ballasts and reliable performance in commercial and industrial lighting applications. The 70-watt rating offers a balance of energy efficiency and high output, while the warm-toned light helps create a welcoming outdoor ambiance. This bulb is a common replacement option for existing HID fixtures that use ANSI code S62 ballasts.
GRUOTVSZAK LU70/MED High Pressure Sodium Light Bulb
This 70-watt HID bulb by GRUOTVSZAK offers 6500 lumens and a consistent 2100K color temperature, providing a bright, warm glow ideal for outdoor spaces. The LU70/MED design fits standard E26 sockets and aligns with ANSI S62 ballast configurations. With a claimed lifespan exceeding 24,000 hours, this bulb targets long-term fixture maintenance reductions for commercial properties and industrial sites. The clear bulb enhances lumen output and allows color rendering to remain strong in outdoor conditions.
Compatibility with ANSI ballast codes and its robust life expectancy make it a practical replacement for aging HPS installations. The bulb’s brightness and enduring performance are particularly beneficial for areas requiring high visibility and reliable nighttime illumination.
Bluex Bulbs LU50/MED High Pressure Sodium Bulb (3 Pack)
The Bluex Bulbs LU50/MED set includes three 50-watt HPS bulbs with a mid-base (E26) and a clear glass finish. Producing around 3600 lumens at 2100K, these bulbs provide strong outdoor illumination suitable for streets and parking areas. The bulbs are designed for long service life, with an expected life of roughly 24,000 hours, making them a cost-effective option for large outdoor lighting projects. They comply with ANSI code S68 ballast requirements, so fixture compatibility should be verified before installation.
Choosing a 50-watt option can help optimize energy use in fixtures where 70-watt or higher lamps would exceed lighting needs. The compact 2.16 inch diameter and tall profile enable use in compact HID luminaires without sacrificing performance.
Rossesay LU150/MOG 150W High Pressure Sodium Bulb
The Rossesay LU150/MOG is a 150-watt HPS bulb with a mogul base (E39). It delivers about 16,000 lumens at 2100K, designed for outdoor street lighting and high-illumination requirements. With a long service life exceeding 20,000 hours, this bulb provides extended use in demanding environments. The bulb’s clear exterior and substantial size are typical for high-output outdoor luminaires, contributing to improved nighttime visibility for large areas.
Compatibility with E39 mogul fixtures makes this bulb ideal for high-traffic outdoor applications. Its generous lumen output can help achieve uniform lighting across wide spaces, reducing dark spots and enhancing safety and security in public zones.
GRUOTVSZAK LU100/MED High Pressure Sodium Bulb
The LU100/MED by GRUOTVSZAK is a 100-watt HPS bulb with an E26 medium base. It produces 9000 lumens at 2100K and is designed for prolonged operation with a life expectancy of over 24,000 hours. The bulb’s clear glass maximizes light output, making it suitable for industrial and outdoor lighting installations requiring higher brightness levels in larger areas or longer run times.
General compatibility with ANSI S54 ballast systems helps ensure fixture compatibility. This bulb offers a balanced option between lumen output and energy use for spaces that demand strong nighttime illumination without unnecessary overkill.
Buying Guide: Key Considerations For High Pressure Sodium Lighting
- Fixture compatibility: Verify ANSI ballast code compatibility (S62, S68, S54, etc.) and base type (E26 or E39 mogul) before purchasing bulbs to prevent ballast and socket mismatches.
- Brightness vs. area: Higher lumens deliver more coverage. For wide outdoor areas or high-traffic zones, bulbs in the 9000–16000 lumen range are common; smaller venues may suffice with 3000–6000 lumens.
- Color temperature: Most outdoor HPS lighting operates around 2100K, offering warm amber tones. This can enhance perception of surroundings but may affect color rendering for some tasks.
- Lifespan and maintenance: Lamps with longer lifespans reduce replacement frequency and maintenance costs. Look for ratings around 20,000–24,000 hours for commercial deployments.
- Base and form factor: Ensure the bulb’s physical dimensions fit the luminaire housing. Mogul-based bulbs are larger and suited for higher-output fixtures, while standard E26 bases suit a wide range of street and parking lot lights.
- Economic and energy considerations: While HPS lamps are efficient, consider total energy costs and fixture efficiency when planning long-term lighting budgets, especially for large sites.
- Replacement strategy: If upgrading a fleet of fixtures, assess common ANSI codes and ballast compatibility across fixtures to simplify procurement and maintenance.
- Environmental and safety: Handle HID bulbs with care during installation and disposal. Some bulbs contain materials that require safe handling and recycling per local regulations.
