Brightness
The brighter the installation location, the higher the luminance (specified in cd/m²) should be. A shop window exposed to daylight has different requirements from an indoor corridor.
| Brightness | Environment |
| approx. 350-450 cd/m² | Rooms with controllable lighting conditions |
| from 500 cd/m² | Normal indoor ambient lighting conditions |
| from 700 cd/m² | Strong ambient light, but no direct sunlight |
| from 1,500 cd/m² | Environments with direct sunlight |
