How can you tell if the lighting at a terminal is poor?

Poor lighting at a terminal is recognizable by dark zones on driving routes and loading docks, glare for crane operators and drivers, blurry visibility of markings and obstacles, and frequent complaints from employees about fatigue or headaches. These are not minor annoyances,they are direct safety risks in an environment where heavy vehicles, cranes, and people operate in close proximity. In this article, we answer the most frequently asked questions about lighting problems at terminals.

What are the dangers of poor lighting in a terminal?

Insufficient lighting significantly increases the risk of serious accidents. When driving routes, loading docks, or storage areas are too dark, drivers see obstacles too late, crane operators miss critical reference points, and pedestrians become invisible to vehicle drivers. In an environment with 24/7 operations and heavy equipment, the consequences of a moment of poor visibility are immediately life-threatening.

Furthermore, inadequate lighting undermines operational continuity. Errors during loading and unloading, damaged cargo, delays, and higher failure costs can all be traced back to insufficient visibility. Ports and terminals where every minute counts, that's a cost that quickly adds up.

The most common safety risks in a poorly lit terminal are:

Increased risk of collisions between vehicles and pedestrians
Reduced visibility for crane operators at height
Invisible markings, lanes, and safety zone indicators
Higher chance of loading errors and damaged containers or goods
Increased mental workload and fatigue in employees

What are the most common lighting complaints at terminals?

Operators in cabins and employees on the work floor typically complain about the same issues: uneven light distribution with harsh dark zones, glare from poorly aimed luminaires, yellow or washed-out light that degrades color and contrast, and luminaires that have significantly deteriorated in light output after years of service.

In practice, the following problems are most frequently reported:

Dark spots between light poles, especially on wide lanes or large storage areas
Blinding glare door lighting luminaires that shine directly into the line of sight of crane operators or truck drivers
Poor color rendering which makes colors of containers, markings, or warning signs difficult to distinguish
Flickering or failed luminaires that are not replaced in a timely manner
Excessive light pollution surrounding areas or the public road

Many of these complaints are a result of outdated luminaires or a lighting design that is not suited to the terminal's specific layout and activities.

How do you measure if the lighting at a terminal is sufficient?

The standard measuring instrument is a lux meter, which records the illuminance at working surface height. The measured values are compared with the current standards for industrial outdoor locations and workplaces. In addition to the absolute light intensity, uniformity is also important: the difference between the brightest and darkest areas must not be too large.

A professional lighting measurement must include at least the following steps: measuring multiple points on travel routes and work zones, calculating the average illuminance and the uniformity ratio, and verifying the results against the NEN-EN standards for the relevant workplace. For crane cabins and other specific work positions, additional requirements apply for vertical illuminance and glare limitation.

When is it time to replace terminal lighting?

Terminal lighting needs replacement when luminaires have lost more than 30 percent of their original light output, when maintenance and repair costs structurally exceed replacement costs, or when the lighting no longer meets current safety standards. For traditional luminaires such as high-pressure sodium or metal halide lamps, this typically applies after five to eight years of intensive use.

Concrete signs that replacement is necessary:

Luminaires that emit visibly yellow, orange, or uneven light
Frequent shutdowns or long startup times
Rising energy costs with no change in usage
Employees who chronically complain about poor visibility
Luminaires no longer available for spare parts

The transition to LED floodlights delivers not only better lighting performance but also significant energy savings, which amply justifies the investment in the long run.

What are the requirements for lighting at an industrial site or terminal?

For lighting on an industrial site or terminal, standards from the EN 12464 series (workplace lighting) and the NEN-EN 13201 series (road lighting) apply. The minimum illuminance for driving routes on outdoor areas typically ranges between 20 and 50 lux, while active work zones such as loading docks and crane paths require higher values. In addition, IP classification, impact resistance, and in some cases ATEX certification play a role.

For terminals, the following technical requirements are most relevant:

Illuminance minimum in accordance with EN 12464-2 for outdoor workplaces
Uniformity ratio between minimum and average illuminance of at least 0.25 to 0.40 depending on the zone
IP rating minimum IP65 for outdoor installation, higher classes for dust or water jets
Glare limitation: Low UGR value for zones where operators and drivers work
Color rendering: minimum Ra 65 for general outdoor lighting, Ra 80 or higher for work areas where color recognition is critical

More information about IP and IK ratings can be found on the page about IP and IK ratings.

How to prevent glare from terminal lighting for crane operators and drivers?

Glare is prevented by selecting luminaires with a controlled beam and a low UGR value, and by carefully aligning the placement and direction of light poles with the sightlines of crane operators and drivers. Full-cutoff luminaires, which direct light strictly downwards with no emission above the horizontal axis, are the most effective solution for this.

In the design of terminal lighting, the following measures are decisive:

Use of luminaires with asymmetric or controlled optics that direct light precisely where it is needed
Positioning of light poles outside the direct line of sight of crane cabins
Application of full-cutoff technology to prevent direct light incidence into operators' eyes
Adjustment of mast height and tilt angle to the specific working height of cranes at the terminal.

Glare is not just a comfort issue. For crane operators working at high altitudes with limited visibility, direct light can lead to serious operational errors. A good lighting design always takes into account the specific viewing positions of all users on site. Also see the specific information about lighting for port cranes for more technical context.

Practical example: P&O Ferries Europoort

P&O Ferries had already converted its terminal in Europoort to LED in 2021, using luminaires from a well-known premium brand in the sports lighting market. In practice, that retrofit did not perform in the port. JEL produced a new lighting design based on the existing site layout, supplied new mast structures and installed 119 DarkLicht DL1 luminaires on 30 lighting masts of 26 m. The installation achieves 42 lux with a uniformity of 0.40 to 0.55 and delivers around 66% energy savings compared with the previous LED lighting. The project was completed in 2 weeks, on a terminal that operates continuously.

Poor terminal lighting is therefore not necessarily old lighting. A luminaire that has proven itself in another sector can fall short on a terminal. When there are complaints about shadows, dark zones or high energy use, the light distribution across the site is a better yardstick than the age of the installation.

Sharply focused light puts more light on the site and less stray light into the surroundings. That is why a new lighting design often achieves more than replacing individual luminaires once again.
