After more than a decade in the lighting export business, I have supplied LED street lights for airport projects with authorities, EPC contractors and distributors in many regions. One of the most common questions I get is: "How many lux do we need for night traffic?" The honest answer is that there is no single number. The right level depends on the road type, vehicle speed, traffic volume and local standards. Here is how I explain it to my clients.
Start with the Standards
Lighting levels should follow local regulations and recognized standards such as CIE 115, EN 13201, or IES RP-8, together with the requirements of your airport authority. The figures below are typical reference ranges I see in project specifications. They are not a replacement for official standards, so always confirm with your designer and the authority.
Note also that airfield lighting (runways, taxiways, approach lights) follows ICAO or FAA standards and uses dedicated aeronautical fixtures. The figures here apply to landside and service roads using roadway LED lighting.
Typical Reference Levels by Area
| Area | Typical Average Illuminance | Typical Uniformity (Emin/Eavg) |
|---|---|---|
| Access roads and expressways | 15–30 lux | 0.3–0.4 or higher |
| Terminal forecourts and drop-off zones | 20–30 lux | 0.4 or higher |
| Car parks | 10–20 lux | 0.25–0.4 |
| Apron perimeter and service roads | 10–20 lux | 0.3 or higher |
| Cargo and logistics areas | 20–50 lux | 0.4 or higher |
| Perimeter security roads | 5–10 lux | 0.2–0.3 |
Busy intersections, pedestrian crossings and roundabouts usually need higher levels than straight road sections.
Factors That Change the Requirement
Vehicle speed: Faster roads need higher luminance and longer visibility distance. Slow forecourt areas need more focus on pedestrian safety.
Traffic mix: Roads shared by buses, fuel trucks, cargo trailers and pedestrians need higher uniformity and good vertical illuminance, so drivers can see people early.
Road surface: Dark asphalt reflects less light than concrete, so the same fixture can give different results on different surfaces.
Weather: Rain, fog, and dust reduce visibility. Some airports in coastal or desert areas add a safety margin in the design.
Do Not Chase Brightness Alone
Many buyers think more lux always means safer roads. In practice, glare and poor uniformity can make driving less safe. Bad optics may also disturb pilots or tower controllers. Choose full cut-off or adjustable optics, and confirm mounting height and aiming angle with the airport authority. Color temperature of 4000K–5000K with CRI Ra70+ or Ra80+ also improves visibility and CCTV image quality.
How to Get the Right Light Level
Request a DIALux or Relux simulation showing illuminance and uniformity for every zone
Use typical pole heights of 8m–12m for roads, adjusted by the simulation
Choose high-efficacy fixtures (150 lm/W or above) to reach targets with lower power
Measure actual illuminance after installation and compare it with the design
Allow for lumen depreciation, since light levels fall over time
Quality Keeps the Light Level Stable
A design is only as good as the product behind it. Cheap fixtures lose brightness quickly, and a road designed for 20 lux may drop below the target within two years. That is why strict quality control LED engineering lighting is so important. I always recommend checking LM-79 and LM-80 reports, CE, RoHS and TUV certificates, IP66 protection and 10kV–20kV surge protection, since airports face wind, rain and lightning.
Save Energy with Smart Control
Airports run all night, but traffic is not constant. A smart outdoor light system with dimming, motion sensing and remote fault alerts can reduce energy use by 30%–60% while keeping safe light levels when vehicles are present. If your budget is limited, choose fixtures with NEMA or Zhaga sockets now and upgrade later.
Conclusion
The right lighting level for airport night traffic depends on the road type, speed, traffic mix and local standards, and it must be supported by good uniformity, glare control and stable product quality. Our LED street lights are made under strict quality control LED engineering lighting standards, with aging tests, waterproof checks and surge protection on every batch, so they keep their performance for years. If you are planning an airport project, I recommend Luxsky Lighting as your LED street light supplier.
