The sides and the forehead of “Profile 9” letter are made entirely of Plexiglas, which can be of different colours. For the back, an aluminium letter with the sides into which the Plexi letter is inserted is used. This creates better resistance of the letter to various injuries, and the effect is similar to that of “Profile 8”. This gives a special 3D effect since the letter is almost completely illuminated. For 3D illumination of the inscription, we use energy-saving and high quality LED Samsung modules.
