What Lighting Standards Apply at a Workstation?

Proper workstation lighting is evenly distributed across the entire space and free from elements that could strain the eyes or cause distraction while performing duties. This can be achieved through daylight, artificial light, or most commonly a combination of both sources.

Workplace lighting is divided into two types: general lighting and spot lighting. The first evenly distributes light throughout the room, ensuring good visibility for employees regardless of where they are located. In many professions this is sufficient, but some workstations require exceptional precision. In such cases, task lighting is essential, focusing light exactly where it is needed. It is important to remember that light intensity is not arbitrary – it is regulated by health and safety (H&S) regulations, which specify exact values for different types of workstations.

• 300 lux: sorting, copying, welding, warehouses, packaging zones;
• 500 lux: handwriting, typing, computer work, data processing, conference rooms, precise assembly work, laboratories, food production, kitchen work;
• 750 lux: drafting rooms, precision assembly, sewing machine operation, tool manufacturing, painting, varnishing work;
• 1000 lux: manufacturing of tools, templates, machining instruments, precision mechanics and micromechanics, printing work, prolonged and intensive visual tasks.

Why Is Proper Workstation Lighting So Important?

Workstation lighting standards were not created by accident. Proper lighting has a significant impact on employees’ well-being, concentration, and safety. Insufficient lighting causes faster eye fatigue, drowsiness, and reduced energy, which in turn lowers productivity. In such conditions, mistakes and even workplace accidents are more likely. Well-designed workstation lighting prevents eye strain and allows employees to perform their duties much more comfortably.

Lighting at a Computer Workstation – What Does It Look Like?

Many of us spend most of the day at a computer – in offices, agencies, or corporations. That is why it is so important for employers to ensure proper lighting at computer workstations. Appropriate lighting affects not only eye comfort but also concentration and overall well-being.

For workstations where the computer is not used throughout the entire day (e.g., when part of the duties is performed away from the screen), light intensity should be at least 300 lux. However, if the work is entirely computer-based, the standard increases to 500 lux.

It is worth remembering that a single light source is not enough. Ideally, in addition to general lighting, there should also be a desk lamp positioned so that the light does not glare into the eyes and falls from above – directly onto the keyboard or documents. Light color is equally important – cooler, slightly bluish tones promote concentration and alertness, while warmer, reddish tones may have a calming effect.

Lighting Standards During Remote Work – Do They Still Apply?

Nowadays, with many companies adopting remote or hybrid work models, the question arises whether official H&S lighting standards must also be followed at home. There is no legal obligation to comply with them in a home office; however, these guidelines provide a useful reference for arranging a home workspace to maximize productivity and efficiency. Of course, they are also beneficial for comfort and health. In such cases, it is best to position the computer as close to a window as possible to take full advantage of natural daylight. Additionally, proper overhead lighting should be ensured, and if necessary, a desk lamp should be used. The light should have as natural a color as possible – yellow lighting should be avoided, as it significantly reduces work efficiency.

Proper workstation lighting is not only a matter of regulations but above all of employees’ health, comfort, and safety. Whether in the office or at home, appropriately selected lighting helps maintain concentration, reduces eye fatigue, and improves overall productivity. It is therefore worth remembering the applicable standards and adjusting light intensity and color to the type of tasks performed. This makes work not only more efficient but also simply more pleasant.

FAQ – Workplace Lighting

What should lighting in the workplace be like?

• Workplace lighting should be uniform, free from glare and shadows, and its intensity must be adjusted to the type of tasks being performed.

How many lux are required at a workstation?

• The required light intensity depends on the type of work performed. For warehouse tasks, packaging, welding, or copying, the standard is around 300 lux. For office work, writing, computer operation, or laboratory work, 500 lux is recommended. Precision tasks such as assembly, sewing, or painting require about 750 lux, while micromechanics, printing, and design work may require lighting levels of up to 1000 lux.

What type of light is best for computer work?

• Cool light (4000–5000 K) is most suitable, as it promotes concentration and reduces drowsiness. It is best to combine general lighting with a desk lamp positioned so that the light does not shine directly into the eyes.

Do lighting standards apply during remote work?

• There is no legal obligation to follow H&S standards in a home office, but they are worth using as guidance. Proper lighting (preferably daylight supplemented with neutral artificial light) improves comfort and efficiency during remote work.

How should you choose a desk lamp for work?

• The lamp should have an adjustable arm and shade to direct light precisely onto the workspace. It is best to choose models with adjustable intensity and color temperature, allowing the lighting to be adapted to the time of day and individual needs.
