depot distributes home decoration articles with great success and has built a new logistics centre in Southern Germany for which the construction of a soundproof wall was necessary. Therein the brand lettering is embedded on large scale with translucent acrylic glass. To ensure a uniform light intensity along the full height of the letters, a diffuse reflector was installed at the ceiling of the noise protection wall. The interior is illuminated by Superlight floodlights with wide beam light distribution, mounted at exactly defined positions.
