Bysso
Bysso Acoustic Lighting is where sculptural form meets acoustic performance and lighting precision. Designed by Impact Acoustic, Bysso brings elegance and efficacy to high-ceiling spaces, offering sound absorption and glare-free lighting in one expressive ceiling feature.
Available in two sizes and powered by glare-free reflectors, Bysso delivers up to 3980 lumens of direct output with excellent energy efficiency (up to 99 lm/W). Its light distribution is paired with DALI-compatible dimming, CRI 90+, and four CCT options (2700K–4000K), making it ideal for workspaces, hospitality zones, and public spaces seeking both performance and ambiance.
Constructed with ARCHISONIC® Felt (a material made from 60% post-consumer recycled PET) Bysso is available in 36 carefully curated colors, allowing designers to tailor its impact to their vision. And with a NRC of up to 0.9, it significantly improves room acoustics by absorbing disruptive reverberation.
Sustainable. Architectural. Acoustic. Illuminated.
Bysso transforms ceilings into intentional design statements while making spaces quieter, calmer, and beautifully lit.
