LP Grand Surface Mounted Design: Christian Flindt Concept: The circular luminaire emits a combination of softly diffused, glare-free, downwardly directed light and reflected indirect light from its curved upper rings. A large angled reflector encircles the diffuser and reduces the contrast around the edge. The top reflector is perfectly curved to distribute uplight at a broad angle. A colored outer shade surrounds the reflector and creates an interreflection of light, resulting in a graceful glow on the outside of the top and bottom reflectors. In total, it creates four rings of light surrounding the central diffuser. Finish: Reflector: Matt-white satin finish. ​Outer shade (outside): Matt (black and champagne) or ​gloss (white).
