Featuring third-generation Anidolic extraction optics with low brightness and superior efficacy, light is emitted from both interior vertical planes of the luminaire, efficiently and precisely directed to create a batwing distribution in both the hemispheres. This gives the fixture its low brightness while simultaneously providing the ability to space the runs widely apart for aggressive and sustainable, energy efficient design up to 119 LPW with power densities of typically between 0.30 and 0.50 W/ft2.; Fold combines modern form with advanced technology, engineering ingenuity and an obsessive attention to detail, enabling inspired environments that are luminous and comfortable.; Up to 10′ – 15′ o.c. spacing with 0.45 to 0.75 W/ft.sq. for general area lighting.; Adjust the light to suit the needs of the space and people in the environment.
