What is typically the necessary lumen output for office lighting?

The appropriate lumen output for office lighting is typically in the range of 200-300 lumens per square meter. This range is established based on the need for adequate visual acuity for various tasks commonly performed in an office environment, such as reading, writing, and using computers.

Lighting levels within this range help ensure that employees can work comfortably and effectively without straining their eyes. Higher lumen outputs can provide better visibility and enhance alertness, creating an environment that promotes productivity. Additionally, the specific lumen output may also be influenced by factors such as the color of the walls, the reflectance of furniture and surfaces, and the overall ambient light levels in the space.

Selecting a lumen output below this range might result in insufficient light for the tasks performed, leading to eye fatigue and decreased productivity, while selecting values above this range might lead to glare or discomfort. Thus, the range of 200-300 lumens per square meter strikes a balance that meets the lighting needs of a typical office setting effectively.
