SOL provides comfortable lighting levels and visual comfort that creates a new ergonomic experience. A disc with rounded edges encloses two luminous LED devices designed to diffuse light for direct downlight and indirect uplight that are controlled independently with two integral dimmers in the vertical stem. Special raster optics provide Glare Free illumination that complete the horizontal surfaces of the disc. The very simple shape suggests and allows a complete range of applications, and makes it suitable to the most various contexts.
