Spark Acoustic Lighting
Spark Acoustic Lighting combines minimalist design with acoustic performance to create a glowing halo of calm in noisy spaces. Its circular shape, available in five diameters from Ø400 mm to Ø1600 mm (15.75"–62.99"), brings harmony and acoustic balance to workspaces, hospitality settings, and public interiors.
Crafted from ARCHISONIC® Felt, made with 60% post-consumer recycled PET, Spark offers strong sound absorption with up to 53.82 Sabins in its largest size (ASTM). At just 12 mm thick, it stays lightweight and elegant while delivering impressive performance.
Spark features dimmable direct lighting with 1580 lumens output, a 108° beam angle, and CCT options from 2700K to 4000K, with a CRI 90+ and integrated driver. Choose between opal or microprism diffusers, and 32 curated felt colors to match any design vision.

For daily cleaning, we recommend an alcohol solution (75%), e.g. Pantasept.
If contaminated by dust or fluff, use a feather duster or a regular feather duster.
In case of heavy contamination, treat the material with hydrogen peroxide.
