Panarc downlights and corridor luminaires are designed to provide an economical and high-quality lighting of such areas. Due to their wide beam, downlights with flood lenses provide uniform, horizontal ambient lighting, even from wide luminaire spacings. The corridor luminaires with prism lenses illuminate both side walls along a hallway from the ceiling down to the floor, making the room look bright and welcoming. A sturdy, waterjet-proof construction enables Panarc luminaires to be used in almost any type of building.
