To conserve, to display. To remember. To learn. But there is an apparent paradox (on which to shed light) in the lighting of artworks. Traditional incandescent sources, with the best chromatic performance, contain radiations that go beyond the visible: infrared and ultraviolet. Therefore they can damage art, make it age and desaturating its colors. We need light in order to look at a work of art, but the more we light it, the more it tends to fade. That’s the paradox: the desire for beauty takes it from us, consuming it. But with the new LED light sources, free of harmful radiation, the design of the installation can also concentrate on the emotions of the viewer, with freer composition of the overall arrangement.
