Sunlite 03610 LU70/MED High Pressure Sodium Light Bulb
Best for: mid- to large-area outdoor fixtures that accept a standard E26 base. This 70-watt bulb delivers strong brightness with a 2100K color temperature, making it suitable for high-visibility perimeters and parking areas. Selection reason: reliable, long life and compatibility with common HID fixtures.
- ANSI Code S62 compatible
- 6000 lumens for broad coverage
- Clear glass for straightforward light output
Caution: The 2100K color temperature yields a warm amber glow, which may affect color rendering in some security or inspection tasks.
Woods L1730 Cci Modern High Pressure Sodium Security Farm Light
Best for: outdoor security lighting with built-in dusk-to-dawn control. This 70-watt unit includes a dusk-to-dawn photocell, making it ideal for perimeter lighting around farms, yards, and storage facilities. Selection reason: integrated sensor simplifies operation and reduces energy waste during daytime.
- 70-watt HID lamp included
- Integrated dusk-to-dawn photocell
- Produces strong, broad illumination
Caution: Some fixtures may require additional mounting hardware or wiring to support dusk-to-dawn operation.
LU70/MED High Pressure Sodium Light Bulb, 2 Pack
Best for: users needing redundancy or multiple fixtures in the same project. This 2-pack offers consistent brightness across two lamps, both rated for long life. Selection reason: higher lumen output per bulb and strong compatibility with ANSI S62 ballast systems.
- 6500 lumens brightness
- 24,000+ hours life expectancy
- Compatible with Medium Base E26
Caution: Data shows very high lumen output; ensure outdoor fixtures are weather-rated for HID use to avoid fixture stress.
Satco S3129 2100K 150-Watt ED17 High Pressure Sodium Lamp
Best for: larger outdoor areas or industrial spaces where higher wattage is needed for longer distances. Selection reason: shows a compact ED17 form with 150 watts for extended reach, suitable for long-run fixtures.
- 2100K color temperature
- Ed17 medium base
- Longer form factor for stable installation
Caution: Higher wattage may increase energy use and heat; verify ballast compatibility with a 150W HID lamp.
Satco S3127 2100K 70-Watt Clear ED17 High Pressure Sodium Lamp
Best for: economical replacement in existing 70W HID installations. Selection reason: compact Ed17 base and 2100K color temperature provide consistent light in a cost-conscious package.
- 70-Watt HID lamp
- Ed17 medium base
- Clear lamp for direct light output
Caution: Some fixtures may require ballast compatibility checks to ensure proper operation and longevity.
Buying Guide: Key Considerations for High Pressure Sodium Lamps
What should you verify before buying? Start with base type and ballast compatibility. Most outdoor HID fixtures use an Ed17 or E26 base and require ANSI ballast codes such as S62. Consider lumen output and color temperature: 2100K provides a warm amber light, while higher-lumen options cover larger areas. Check life hours to estimate maintenance windows, and assess fixture enclosure suitability for HID heat and UV exposure.
What wattage do I need?
70-watt lamps suit small to medium outdoor areas, such as walkways and perimeters. For larger areas, 150-watt options deliver more distance and brightness, but use more energy. Match wattage to fixture spacing and illumination goals.
Which base and ballast should I choose?
Most outdoor HID fixtures use Ed17 or E26 bases. Ensure ballast compatibility with ANSI codes (e.g., S62) and verify the fixture’s ballast type before purchasing replacements.
Color temperature and light quality
2100K lamps emit a warm amber light, which affects color rendering. If color discrimination matters (e.g., recognizing signs or license plates), consider how the warm tone impacts visibility in your environment.
Reliability and maintenance
Consider lamps with a long life and easy maintenance access. Fixtures with integrated photocells reduce daytime operation and save energy, but ensure electrical wiring and control systems are up to code.
Installation and safety
Outdoor HID lamps generate heat and require appropriate enclosures, mounting hardware, and weather-rated fixtures. Use sealed fixtures in damp environments and verify that the fixture design supports lamp replacement without compromising safety standards.
Energy and cost considerations
While HID lamps offer high brightness, they consume more energy than LEDs. Assess total cost of ownership, including ballast compatibility, replacement frequency, and maintenance, to determine if HID is the right choice for your site.
FAQ
- What is a high pressure sodium lamp? A high brightness, high-efficiency discharge lamp used in outdoor lighting with amber to warm white color output.
- Are HPS lamps compatible with standard fixtures? Many are; check base type (ED17 or E26) and ballast compatibility with ANSI codes.
- What wattage should I pick for parking lots? For medium lots, 70W often provides adequate coverage; larger areas may benefit from 150W lamps.
- Do HPS lamps require special disposal? Follow local regulations for bulb recycling and hazardous waste handling.
- Can I mix 70W and 150W HPS lamps in the same area? It’s better to standardize within a fixture group to maintain uniform lighting levels.
- What are the advantages of a dusk-to-dawn HID light? It automates operation, improves security, and reduces energy waste by turning lights off during daylight.
