Vior bold acoustic LED pendant light - expansive light source with round, white acoustic panel The Vior bold acoustic LED pendant light combines direct lighting with low glare and a sound-absorbing effect to optimise room acoustics. This is achieved by the round, white acoustic panel, which is made of polyester fibres that are largely produced from recycled PET bottles and processed without chemical binders. Ring-shaped gradations, which are modelled on propagating sound waves, also visually indicate the function of the panel. Brilliant direct lighting is provided by the patented light control system using a lens and microfacet reflector - IP code: IP54 - good colour rendering: CRI > 90 - good glare control: UGR < 16 - externally dimmable with LED phase dimmers - with three slim steel cables (can be shortened before installation) including ceiling brackets for suspension and transparent connection cable - optional canopy available separately (see accessories)
