Designed with Knoll’s FilzFelt fabric, Shaper Sense Acoustic Luminaires come in 62 wool design felt color choices. The Box and Trapezoid pendant—with a Noise Reduction Coefficient of 2.65 and 2.5 respectively—deliver efficacies of 120 lm/W with a lumen output of 4,500. The luminaires have 85% transmissivity, allowing natural daylight to pass through when turned off, and as electric light is needed, become a luminous source for ambient and task applications.
