Bellows

BELLOWS takes the standard linear system in a new direction, its sculptural pleated form introducing rhythm, depth, and character to the ceiling plane. Inspired by the ridged profile of fireplace bellows, this 2.5" aperture luminaire combines bold architectural presence with the reliable performance of a proven workhorse. Its seamless rollout lens delivers smooth, uniform illumination, while Diffused, Batwing, and Asymmetric distributions support a broad range of lighting applications. With multiple lumen packages, high-efficacy performance, BIOS integration for circadian support, and 13 distinctive finishes, BELLOWS brings together technical precision and a refined, tactile design language in one expressive architectural fixture.
