LP Slim Box Recessed Design by: Louis Poulsen A/S Concept: The product family shares a high-efficiency light unit framed in a rectangular housing. The recessed variants emit downwardly directed light, while the suspended and surface-mounted variants provide a combination of primarily downwardly directed and indirect light. Choosing between opal diffusers or micro-prismatic solutions, the glare and visual expression can be balanced as desired. The light egress emphasizes the design detail in the housing, ensuring a comfortable and subtle yet distinct design. Finish: White or black, powder coated or clear lacquered, pickled aluminium.
