Umbra Round
Designed for those seeking acoustic clarity and visual warmth, Umbra Round Acoustic Lighting brings together sound absorption and subtle illumination in one refined, circular form. With its sculptural simplicity and customizable size range, it suits everything from intimate lounges to large-scale atriums.
Crafted from ARCHISONIC® Felt (made with 60% post-consumer recycled PET) Umbra Round achieves powerful acoustic performance and offers a stunning palette of 36 curated colors. Available in five sizes from Ø400 mm to Ø1600 mm, each fixture delivers direct light output via opal or microprism diffusers.
With a CRI of 90+, 0.1% DALI/DSI dimming, and CCT options from 2700K to 4000K, Umbra Round provides both ambiance and clarity. Despite its soft appearance, it performs with strength, offering up to 55.97 Sabins of absorption in its largest form.
Round, radiant, and responsible. Umbra Round elevates acoustic design with an understated yet impactful presence.
