Illuminance ranges

The illuminance that is recommended for a specific activity will partially depend on both the nature of that activity as the design of the particular area (especially the brightness).

The table shows the recommended illuminance for different kinds of areas and activities, based on the beforementioned specified scale. The values are averages of minimal illuminance levels required by the specific task. Because of this reason levels of illuminance must never be below these values.

Recommended illuminance levels (lux)Type of activity

30

Walkways and outdoor work activities

100

Walkways, simple orientation or short visits

150

Rooms that are not constantly used for professional means

300

Visually simple tasks

500

Visually average tasks

750

Visually demanding tasks

1000

Extremely visually demanding tasks

1500

Tasks with special visual demands

2000

Strenuous visual tasks 

The values are applicable for normal visual circumstances, taking the next factors in to account:

  • Demands for visual tasks
  • Security
  • Psycho-physiological aspects, like visual comfort and wellbeing 
  • Sustainability
  • Experience

Illuminance should be elevated when:

  • There is an unusually low amount of reflective surface present in the room
  • Visual performance is paramount
  • Mistakes are expensive to correct
  • Precision or a higher productivity is of great importance
  • Visual capacities of the worker are below average

Lower levels of illuminance are permissable:

  • There is an unusually high amount of reflective surface present in the room
  • Speed or precision is not important
  • The task is only executed rarely
