Level of reflection

The degree of reflection indicates the percentage of the luminous flux of an area. This applies that bright areas such as white walls have a very high degree of reflection and therefore a lot of light is reflected back into the room. Dark areas, on the other hand, have a very low level of reflection and "swallow" a large part of the light, so to speak.

In general, the darker a room can be remembered or equipped, the more light is ultimately needed to reach the same illuminance on an area as in a light space. The degree of reflection must therefore be taken into account, especially in the case of visual tasks such as workplaces, because good lighting plays a very important role here.

Typical degrees of reflection on which you can orient yourself are among other things:

• White walls have a reflection level of up to 85%
• Light wood cladding has a degree of reflection of approx. 35%
• Red bricks only have a degree of reflection of around 15%

When lighting a room, it is therefore always necessary to take into account its nature or color design. Ceilings and walls should have higher levels of reflection for balanced brightness impression and are therefore not painted too dark. In the case of furniture or work surfaces, the degree of reflection depends heavily on the respective requirements or activities in the room. The soil, on the other hand, does not play too big, which is why around 20% to 40% are sufficient.
