By accepting two different diffusers, Schlüter-LIPROTEC makes it possible to create different lighting effects. If the diffuser can be seen by the viewer when he looks at it directly, then we are talking about "direct illumination".
As an example, the Schlüter-LIPROTEC-VBD diffuser for indirect light distribution offers an additional direct light strip of 3 mm width when viewed from the front. However, this light strip is not considered to be blinding, since the amount of light is reduced at this location of the diffuser.
In most cases, an "indirect distribution of light" is realised via an adjoining wall covering. The viewer is not looking directly into the light area.
This way, using two diffuser systems for the same receptacle profile, different light effects can be achieved. Installing the diffusers is simple: Just clip them on!
