Assessing lighting quality: more than just illuminance
Don't plan lighting on the basis of measured values alone. Illuminance offers guidance, but it does not describe the quality of a space.
So ask your customers how they want to experience the space. Where and how do they feel safe, focused, or at ease?
Only when you combine measurable requirements with perception, atmosphere, and use does light create quality of life.

The most important points
- 1Evaluate lighting quality not by illuminance alone, but together with perception, atmosphere, and use.
- 2Combine directional light for contrast and modeling with a soft general lighting for orientation and atmosphere.
- 3Use standards as a minimum benchmark, not as a design objective – visual comfort only begins beyond them.
