Keystone Technologies 70W HPS Ballast Kit (HPS-70R-1-A-KIT)
The Keystone HPS-70R-1-A-KIT includes an ignitor and bracket, designed for 120V high-pressure sodium installations. It’s best for facilities needing a complete ballast kit with mounting hardware and a built-in ignitor for quick replacement. This option is a solid choice for outdoor security lighting and parking areas where a compact, ready-to-install ballast is preferred.
Who it’s best for: building managers and maintenance crews needing a turnkey 70W ballast kit with ignition in a compact form factor. Why selected: the kit consolidates essential components for straightforward retrofits or new builds on S62-compatible fixtures.
Caution: verify fixture compatibility with the included ignitor and bracket, and confirm the ballast’s fit in your enclosure before purchasing.
Sunlite LU70/MED High Pressure Sodium Bulb, 70W
This Sunlite 70W HPS bulb uses a MED base (E26) and ANSI code S62, delivering about 6000 lumens at approximately 2100K. It’s suitable for street, parking lot, and perimeter lighting where a bright, warm tone is desired. The clear glass design helps maintain light output consistency in outdoor fixtures.
Who it’s best for: facilities needing a straightforward bulb replacement in existing HID street or area lighting. Why selected: widely compatible with S62 ballasts and typical medium-base fixtures. Caution: ensure your ballast supports 70W HPS bulbs and that the color temperature fits your lighting plan, as 2100K is quite warm.
Advance e-Vision IMH70DLFM 70W Ballast
The Advance e-Vision IMH70DLFM is an electronic ballast designed for 70W metal halide fixtures with pulse start operation. It supports 120/277 volt inputs and is specified for ANSI M98, M139, or M143 configurations with a high power factor around 90%. This makes it suitable for higher-efficiency applications and environments with variable electrical supplies.
Who it’s best for: facilities using 70W metal halide lamps that want improved power factor and stable operation across 120/277V. Why selected: it combines pulse-start electronics with flexibility for common commercial lighting circuits. Caution: confirm your existing HID setup uses compatible ANSI codes and that the fixture’s dimming or control gear isn’t impacted.
Wadoy LU70/MED 70W HID Bulb, 3 Pack
This 3-pack from Wadoy includes 70W LU70/MED HPS bulbs with an E26 base and ANSI S62 compatibility. Each bulb delivers around 6000 lumens at 2100K, making them a practical option for multiple lighting points or ongoing replacements in outdoor security and parking areas.
Who it’s best for: buyers needing multiple bulbs for several fixtures or for bulk stocking. Why selected: cost-effective packaging and reliable HID performance in S62-compatible systems. Caution: verify supply voltage and ballast compatibility across all fixtures to avoid mismatched operation in some units.
GRUOTVSZAK LU70/MED 70W Bulbs (2 Pack)
The GRUOTVSZAK 2-pack provides 70W LU70/MED bulbs with ED17/MED base and ANSI S62 compatibility. Each bulb delivers about 6500 lumens at 2100K, with a long life exceeding 24,000 hours. Clear bulbs support uniform outdoor illumination in security and parking applications.
Who it’s best for: teams needing bulk bulbs for a multi-fixture outdoor installation. Why selected: high brightness and long life align with frequent replacement cycles. Caution: color temperature is warm; if a cooler appearance is needed, consider alternatives with higher color temperatures.
Buying Guide: What To Consider When Choosing a 70W HPS Ballast Or Bulb
- Ballast type: Do you need a complete ballast kit with ignitor (electronic ballast) or a simple replacement bulb for existing ballasts?
- Base compatibility: Confirm E26/MED base compatibility with your fixtures and whether ANSI code S62 is required.
- Ballast compatibility: Ensure the ballast supports your lamp type (HPS) and its voltage (120V vs 277V, etc.).
- Application environment: Outdoor vs indoor, parking lot, street lighting, or security lighting—all influence brightness and color temperature needs.
- Color temperature and brightness: 2100K yields warm amber light and around 6000 lumens; consider your lighting design goals when selecting color and output.
- Lifecycle and maintenance: Lifespan claims (e.g., 24,000 hours) can guide replacement scheduling and inventory planning.
- Packaging needs: If multiple fixtures require bulbs, multibulb packs may reduce ordering frequency and costs.
Frequently Asked Questions
- What is a 70W HPS ballast used for?
It powers 70-watt high-pressure sodium lamps, typically in outdoor lighting applications like parking lots and street lighting.
- What does ANSI S62 mean for bulbs?
ANSI S62 indicates compatibility with certain HID ballasts; ensure your fixture and ballast support this code.
- Is a ballast kit better than a bulb replacement?
A ballast kit is preferred when replacing the ballast assembly (including ignitor and mounting hardware) for a full retrofit or upgrade.
- Can I mix 70W HPS bulbs with other wattages in the same fixture?
No. Use matched ballast and bulb wattage to avoid electrical and performance issues.
- How long do 70W HPS bulbs typically last?
Lifetime varies by model, but many are rated around 20,000 to 24,000 hours under normal operation.
- What should I check before buying?
Fixture base type, ballast compatibility (120V or 277V), ANSI code, and whether you need a complete kit or a bulb replacement.
