Modular systems in extruded aluminum for ceiling, suspended and total or border built-in installation for application in the plasterboard. Available in diffused light with polycarbonate screen or micro prismatic screen (light diffusion through internal reflection). Double screens: the first one is disposable for smoothing, stucco and painting operations, while the second in polycarbonate is permanent. Possible horizontal or vertical applications. Profiles can be installed based on different creative needs: horizontal or vertical connection joints with 90° edges, or T or X joints are available. Lit edges are available in the LED version to create uninterrupted lines. Accessories are available, like the “throttle” micro adjustment mechanisms that favour a proper and easy installation in the plasterboard. LED or fluorescent solutions feature instead a quick-anchoring system to simplify the installation of electric components. There are various electrification options, according to the structures and systems. Profiles installations are also available in dimmable version, to adjust the light intensity as desired for every moment of the day. Upon request, based on design needs, versions with integrated emergency light are available. The Profiles solutions of Panzeri catalogue provide minimal lighting where light bundles design the space.
