The patented FLUVIA system allows for quick and easy installation of Trimless luminaires. The new X-Trimless system allows the luminaire to blend into the ceiling or wall without affecting the uniformity of the surface. The transition between the installation surface and the luminaire is unnoticeable, avoiding irregularities due to the material or the seams if the material is incorrectly applied. The design of the new X-Trimless system allows the luminaire to be more securely attached to the installation surface, ensuring that the luminaire and the surface will remain in good condition even with prolonged use. The X-Trimless system can be used to group luminaires, with a minimum distance between them, thanks to its system for joining accessories. This innovative feature, unique in the market, enhances the creativity of the interior designer, makes for an easy installation and guarantees a perfect result. The design of the weave and its non-porous material means that only the necessary material is absorbed. The rest can be simply wiped away. This avoids problems with the luminaire or its mobility.
