Kelvin Edge base table lamp - Flos

The Kelvin Edge is the evolution of Flos's historic Kelvin lamp. In this version, the light comes from a thin rectangular LED head with Edge Lighting optics : a system that guarantees uniformity, extremely high color rendering, and total visual comfort , without glare.

The entire body of the lamp is articulated, with double jointed arms and a swivel head , which allow for precise adjustment of the position and inclination of the light, perfect for desk work.
