The Artemide Lineacurve LED Wall/Ceiling Light takes advantage of a simple construction in order to create many light options; including but not limited to: function, efficiency, color temperature and CRI. This not only is beneficial for large-scale projects (namely commercial), but the ability to customize the light you want is attractive for residential installation as well. In profile, the bar is slightly concave, allowing more light to diffuse in all directions—direct and direct/indirect alike.
