French designer FX Balléry casts a Fine line with this linear steel prism for Paris-based Arpel. The LED light source spreads softly glowing illumination that is filtered through an aluminum diffuser. Lighting levels are at 4 preset options, via a touch switch. Or choose the unique "Green Mode" with a long press on the switch and the lamp automatically adjusts to its surrounding light—and according to whether someone is present. LED energy consumption of just 11 watts, with 50,000-hour lifetime usage.
