Poor lighting in a factory can be truly dangerous — and that's no exaggeration. Insufficient light increases the risk of trip accidents, incorrect operations on machinery, and missing hazardous situations. This applies to every industrial work environment, from production halls to outdoor areas. Below you will find answers to the most concrete questions about risks, standards, and solutions related to workplace lighting.
What dangers arise from insufficient lighting in the workplace?
Those who think a few sparse fixtures are sufficient underestimate the risk. Employees have a harder time seeing obstacles, markings, and dangerous zones, resulting in trips, collisions with internal transport, and errors when operating machinery. In environments where sharp materials, heavy loads, or hazardous substances are handled, these errors can have serious consequences.
Furthermore, the dangers are not just physical. Poor lighting also affects concentration and alertness. Employees who work in poorly lit spaces for extended periods experience fatigue and a reduced response time more quickly — especially with repetitive tasks or work near moving machine parts.
- Increased risk of trip and fall accidents due to invisible obstacles or differences in level
- Danger in internal transport due to poor visibility of forklifts and mobile equipment
- Machine operation errors due to insufficient visibility of control panels and safety indicators
- Reduced visibility of escape routes and emergency exits in emergencies
- Increased risk of eye strain, headaches, and loss of concentration with prolonged exposure
How many lux are required in an industrial work environment?
The European standard NEN-EN 12464-1 specifies the minimum lux required in industrial workplaces. For general production areas, a minimum of 300 lux on the work surface generally applies. For precision work, such as assembly or quality control, this increases to 500 to 1000 lux or more. Outdoor areas and traffic routes fall under the EN12464-2 standard, where the required illuminance depends on the activity taking place there.
Lux is a measure of illuminance, but it also concerns the distribution of light. A space with an average sufficient lux level but large dark zones does not meet the standard. Uniformity—the ratio of the lowest to the average illuminance—is therefore just as important as the absolute lux level. A good lighting solution ensures even coverage without dark corners or overexposed areas.
Do you want to know exactly which standards apply to your specific work environment? Via professional lighting advice The correct illuminance is determined per zone based on the activities taking place there.
What are the consequences of poor lighting on productivity and errors?
The impact reaches beyond safety alone. Employees work more slowly when they have difficulty distinguishing details, and the chance of quality errors increases when products or materials are not clearly visible. This has direct consequences for output, rejection rates, and overall business efficiency.
Research in occupational hygiene shows that the work environment, including lighting, is one of the most decisive factors for employee concentration and performance levels. Good lighting not only supports safety but also accuracy in tasks requiring visual effort—consider reading measuring instruments, checking weld seams, or sorting materials.
in the heavy industry Furthermore, the combination of physically demanding conditions and poor lighting further increases the risk of errors and fatigue. An investment in better lighting in these environments quickly pays for itself through less downtime, less rework, and lower absenteeism.
When does industrial lighting no longer meet the standard?
The fact that a fixture is still lit does not automatically mean it still meets requirements. Industrial lighting falls short when the measured illuminance drops below the required lux levels, the uniformity of light is too low, or when the fixtures are no longer suitable for the environmental conditions. This can be due to outdated fixtures, defective lamps, dirty optics, or a changed layout of the workspace.
Fixtures lose light output over time, even if they are still functioning. This is called lumen depreciation or light depreciation. A fixture that provided 500 lux upon installation may only produce 300 lux after years of use without visible malfunctions. Therefore, periodic light measurements are necessary to check if the installation still complies with current standards.
Additionally, IP and IK ratings play an important role. Luminaires in damp, dusty, or mechanically stressful environments must demonstrably be protected against those conditions. Read more about what these ratings mean on the page about IP and IK ratings.
What is the difference between glare-free and non-glare industrial luminaires?
Dazzling fixtures emit light at a wide angle, including towards the user's eyes, leading to direct or indirect glare. Non-glaring fixtures use special optics or shielding to direct light towards the work surface without the light source itself being directly visible to the observer. This difference has significant implications for safety and visual comfort.
Glare is a serious safety risk in the workplace. When an operator, crane operator, or forklift driver is temporarily blinded, it can lead to dangerous situations. This is unacceptable in environments with moving equipment or work at height. Non-glare optics—such as the full-cutoff technology used in specialized industrial fixtures—prevent this by keeping the light completely below the horizon.
For applications in machinery and mobile equipment Non-glare LED work lights and therefore the obvious choice. They offer clear work lighting without bothering bystanders or drivers of other vehicles.
How to improve lighting in an existing production hall?
An improvement doesn't have to happen all at once. By following a structured approach, it's often possible to upgrade lighting step by step without halting production.
- Perform light measurement: Map the current lux levels per zone and compare them with the applicable standards for the respective activities.
- Lighting design development Determine the required illuminance, uniformity, and luminaire type for each work zone based on the tasks performed there.
- Luminaire selection tailored to the environment: Consider temperature, dust, moisture, vibration, and other environmental factors when selecting fixtures.
- Installation plan Align the installation with production schedules to minimize downtime. Modular systems make this easier.
- Schedule aftercare and maintenance: Create a maintenance plan for periodic cleaning and inspection of the fixtures to maintain light output.
When choosing new fixtures, it is also useful to look into financing options. Energy investment allowance A portion of the investment in energy-efficient LED lighting can be made tax-advantageous.
Practical example: Van Gelder – Full-Cutoff Specialization
A concrete example of how lighting choices have direct safety implications is the project at Van Gelder. The central challenge in this infrastructure project was to illuminate an active work environment where heavy machinery and pedestrians operate simultaneously. Glare for machine operators was a real and unacceptable risk.
The solution lay in the application of full-cutoff luminaires: luminaires that direct light exclusively downwards and do not emit light above the horizontal line. This eliminated glare for vehicle and crane operators, while ensuring the workspace itself was provided with sufficient and uniform illumination. At the same time, the luminaires had to withstand the mechanical stress of an active construction site — vibrations, dust, and varying weather conditions called for robust IP and IK certified designs.
An important lesson from this project is that choosing the right type of optics is not just a matter of comfort, but a direct safety measure. Standard fixtures would have led to dangerous situations here. The combination of directed light distribution, high protection classes, and a well-thought-out mounting plan proved to be decisive.
