The bulb’s ANSI code S62 compatibility ensures it works with common ballast configurations. This option is ideal for retrofit projects where older HID lamps are being replaced with reliable, high-intensity outdoor lighting solutions.
Woods L1730 Cci Modern High Pressure Sodium Security Farm Light
The Woods L1730 Cci Modern security light includes a 70-watt HPS lamp in a powder-coated housing, designed for reliability in outdoor or perimeter lighting scenarios. It ships with a dusk-to-dawn photocell, automatically turning off during daylight and activating after dark to maintain continuous illumination when needed. The fixture delivers around 6,400 lumens of light output, helping illuminate walkways, entries, or fenced perimeters with clear, bright coverage. The integrated design simplifies installation for property owners seeking a ready-to-use security lighting solution.
Highlights include straightforward 120 V operation, a durable housing, and a complete lighting package that minimizes maintenance. The dusk-to-dawn control is especially useful in reducing energy waste by aligning output with ambient light levels, a practical consideration for security and safety-focused outdoor lighting deployments.
LU70/MED High Pressure Sodium Light Bulb, 2 Pack
This 2-pack of 70-watt LU70/MED bulbs offers strong luminance for outdoor applications, with an ANSI S62-compatible ballast fit and a medium E26 base for versatile installation. The bulbs provide up to 6500 lumens of brightness with a clear bulb design and a 2100K color temperature, aiming to maximize visibility in parking areas, street lighting, and perimeter security. With a claimed life over 24,000 hours, these lamps are positioned as a low-maintenance option for long-term outdoor projects, balancing brightness with efficiency across frequent on/off cycles typical in public or commercial settings.
Considerations include compatibility with existing HID fixtures, ballast efficiency, and the potential need for appropriate thermal management in enclosed fixtures. The high-lumen output is advantageous for broad-area illumination but may require attention to glare in glare-sensitive locations.
Satco S3129 2100K 150-Watt Clear Medium Base ED17 HID Lamp
The Satco S3129 is a high-pressure sodium lamp rated at 150 watts with a clear ED17 medium base. It’s designed to deliver consistent outdoor lighting performance, making it a solid option for larger-area fixtures where higher output is required.

It’s a suitable choice for retrofits where existing HID infrastructure is preserved but a brighter, uniformly lit outdoor space is desired.
Buying Guide: Key Considerations For High-Pressure Sodium Lamps
- Fixture and ballast compatibility: Ensure the bulb’s base (ED17, E26/MED) and ANSI ballast code (e.g., S62) match your lighting fixture. Mismatches can reduce performance or cause failure.
- Lumen output and coverage: Higher lumens improve area coverage, but require appropriate ballast and thermal management to maintain performance over time.
- Color temperature and ambiance: Most outdoor HPS lamps emit a warm, amber glow around 2100K. This can affect visibility contrast and color rendering; consider the environment and security needs when selecting bulbs.
- Longevity and maintenance: Lamps with longer rated life reduce replacement frequency, but consider replacement logistics for hard-to-reach fixtures.
- Power and energy considerations: HPS lamps offer strong efficiency for their era, yet LED alternatives may provide longer-term energy savings. Weigh upfront cost against long-term operational costs and maintenance cycles.
- Environmental and safety factors: Outdoor installations should consider weather resistance, housing protection, and glare control to prevent light trespass and ensure user safety.
- Replacement timing: Plan for ballast and receptacle health; sometimes multiple components must be serviced together to maintain consistent illumination.
- Availability and sourcing: Check if the exact bulb shape, wattage, and base are readily available from trusted suppliers to avoid compatibility gaps during replenishment.
- Compliance and codes: Verify local regulations regarding outdoor lighting levels and color temperature, particularly for public or commercial sites.
- Fixture life cycle planning: For large facilities, coordinate bulb replacements around maintenance windows to minimize downtime and ensure continuous security lighting.
In summary, high-pressure sodium lamps remain a practical option for wide-area outdoor lighting where robust brightness and long service life are priorities. When choosing among the options, consider ballast compatibility, lumen output, and installation constraints to ensure dependable lighting performance across nights and seasons.
