✅ Key Comparison:

Beam Angle     Applicable Height        Beam Coverage                                       Applicable Scenarios                                                    Pros and Cons

90°                    8-12m                            Concentrated, intense illumination        Automotive manufacturing/precision machining         ✅ High illumination ❌ Requires denser installation

120°                  6-9m                            Wide and uniform coverage                     Warehouses/logistics centers                                       ✅ Reduces the number of fixtures ❌ May be too bright for mid- and low-rise buildings

💡 Professional Advice:

🔹 High-bay lighting (≥10m) → 90° batwing distribution is recommended (reduces light decay)

🔹 Ordinary factories (6-9m) → 120° can reduce the number of fixtures by 20%

✅ Luminous Efficacy Calculation Formula:

Luminous Efficacy (lm/W) = Total Luminous Flux (lm) ÷ Input Power (W)

Our high-bay lights use high-quality CREE/OSRAM LEDs. Actual measured data is as follows:

Model     Nominal Power (W)          Luminous Flux (lm)             Actual Luminous Efficacy (lm/W)                     Industry Average Comparison

150W                150W                             24,000lm                                     160lm/W                                                     Standard: 120lm/W

200W               200W                            32,000lm                                     160lm/W                                                     Standard: 130lm/W

300W               300W                             51,000lm                                     170lm/W                                                     Standard: 140lm/W

🔹 Industry High-End = 160-180lm/W

🔹 Standard Brand = 100-130lm/W

🔹 Our advantages: dual-channel constant current drive, stable light efficiency ±3% fluctuation

⚠️ Wide voltage range doesn't mean universal! Pay attention to details:

✅ Real Capabilities:

🔹 Automatic 100-277V adaptation (no adjustment required)

🔹 Surge Protection: 4KV composite wave protection (meets IEC61000-4-5)

🚨 Notes:

A voltage stabilizer is required for voltage fluctuations >±10% (especially in African/Southeast Asian markets).

The system will still work if the neutral and live wires are connected reversely, but an alarm will be triggered.
