Founded in 2009, Hengjian (HJLED Lighting) has grown into a high‑tech, ISO9001-, BSCI-, TUV- and ITS‑certified enterprise in Cixi, Zhejiang Province, China, with nearly 100 series of LED products—including AC street lights and high bay lights. Serving both domestic and export markets, HJLED combines innovative design with robust manufacturing capacity.
⚡ AC Street Light: Grid‑Powered Illumination at Scale
HJLED’s AC street lights are engineered for reliable city and road lighting using traditional AC mains power (typically 100–277 VAC or AC220 V). These fixtures feature:
- High-efficiency LED chips such as 5050 or 3030 types delivering 140–160 lm/W, ensuring bright output at lower wattage.
- Long lifespan (up to 70,000 hours), with instant-on capability and minimal warm-up behavior unlike older HID lamps.
- Weatherproof construction, typically rated IP66 to withstand outdoor conditions including dust, rain, and temperature extremes ranging from –40 °C to +50 °C.
In comparison to traditional HID sources like HPS or metal halide, LED street lights offer better energy efficiency, better color rendering, reduced glare, and significantly lower maintenance costs.
Applications include highways, residential roads, parking lots, campuses, and commercial properties.
???? High Bay Light: Industrial-Grade Illumination for High Ceilings
HJLED also offers High Bay lights, a staple in industrial and commercial facilities such as warehouses, factories, gymnasiums, and sports halls.
- Available in multiple series (e.g., Sealion, Firefly, Golden Frog, Sea Anemone), covering from 30 W to 720 W with luminous efficacy up to 140 lm/W.
- These lights support a wide input voltage range (100–277 VAC, 347–480 VAC, or 24–48 VDC/AC) and are often rated for high ambient temperatures, some up to 80 °C.
- High durability: Many are rated IP66 for dust and moisture resistance and come with robust warranties of up to 5 years.
High bay fixtures provide uniform, intense downward illumination that ensures coverage of large floor areas even when mounted 20–30 ft above the ground.
???? Why AC Street and High Bay Lights Matter Together
1. Energy Efficiency & Operational Savings
Compared to HID options, LED AC street and industrial lights deliver up to 50% lower energy use, longer lifespan, and reduced maintenance frequency. Many manufacturers cite 10–15 years of effective service life with minimal lumen depreciation.
2. Improved Lighting Quality
AC LED luminaires offer instant-on, high-CRI options for better visibility, superior color rendering over older sodium/metal halide technology, and better glare control due to directed optics and lenses.
3. Safety & Compliance
CE, RoHS, UL, and other safety certifications are standard. However, users should be cautious of off-brand fixtures that may cut corners—review claims carefully and seek validated certifications.
4. Versatility in Installation
AC street light are generally pole or wall-mounted directly to mains, while high bay lights come in pendant, bracket-mounted, or suspended configurations—tailored to facility layouts and heat dissipation requirements.
????️ End‑User Tips: Choosing AC Street Light or High Bay Light
| Feature | AC Street Light | High Bay Light |
|---|---|---|
| Typical Wattage | 30 W–150 W (e.g. 150 W LED ≈ 20,000–24,000 lm) | 30 W–720 W, custom to ceiling height & area |
| Input Voltage | AC 100–277 V or 220 V | AC 100–277 V up to 480 V or DC as needed |
| IP Rating | IP66 (outdoor exposure) | IP65–IP66 (indoor humidity, dust, or wash-down) |
| Color Temperature (CCT) | 3000K–6500K | Typically 4000K–5000K for industrial clarity |
| Mounting Options | Pole or wall bracket | Pendant, hook, suspension, bracket mount |
| Warranty | Commonly 3–5 years | Often 5 years or more |
Considerations Before Purchase:
- Project Requirements: Determine height mounting, light uniformity, lumen output needed.
- Certifications: Ensure compliance—CE/RoHS for Europe, UL/ETL for US, across both product lines.
- Colour Rendering & Glare: For street lights, aim for CRI >70; for warehouses, choose 4000–5000K.
- Ambient Conditions: Select products rated for local climate—especially high bay lights in hot environments that require thermal management.
- Safety & Installation: High bay installation requires planning for wiring, ceiling structure, and possible suspension systems; street lights require pole and conduit compatibility.
✅ Summary
HJLED Lighting’s portfolio of AC street lights and High Bay light addresses both outdoor urban lighting and indoor industrial illumination needs. Their fixtures merge high-efficiency LED technology, rugged designs, smart optics, and safety certifications into long-lasting, cost-effective lighting solutions.
AC street lights offer maintenance-friendly, instant-on highway and city lighting with cool efficiency and better visibility.
High bay lights deliver powerful, uniform indoor illumination essential for warehouses, factories, and large commercial spaces.
Choosing between them—or deploying both—depends on your environment: city roads, campuses, or high-ceiling work areas.
