Lighting is one of those office elements that we only notice when it is bad. An interior that is too dark tires the eyes, one that is too bright and cool can be perceived as unpleasant, and reflections on the screen can ruin even a well-designed workstation. It is worth dividing the topic into three independent issues.

Light intensity

The amount of light should be adapted to the type of task. Working with a screen requires a different level than reading documents or working with materials and samples. A good practice is to combine general lighting with local lighting, which the user can turn on when needed. Uniform, strong light throughout the entire space is rarely optimal.

Color temperature

Cooler light promotes concentration and works well in work zones, while warmer light is perceived as more comfortable and is suitable for relaxation and informal meeting zones. Differentiating the color temperature between zones also helps to intuitively understand the purpose of a given place.

Glare and reflections

The most common problem is not the lack of light, but its improper distribution. A luminaire visible directly in the field of vision or reflecting off the screen causes fatigue and reduces image contrast. Luminaires with appropriate shielding, positioning workstations parallel to the rows of luminaires, and avoiding glossy desk surfaces all help.

Daylight

Access to daylight affects well-being and the daily rhythm, which is why workstations should be planned so that as many people as possible have contact with it. At the same time, solar control must be provided, because on sunny days the same window becomes a source of glare. Roller blinds or adjustable blinds are essential here.

Summary

Good office lighting combines the right intensity, well-thought-out color temperature, and the elimination of glare, while maximizing the use of daylight with the possibility of limiting it. The most common mistake is focusing solely on the amount of light while ignoring where it comes from.
