Ondaria has Zumtobel going round in circles

Ondaria has Zumtobel going round in circles

Zumtobel’s new circular luminaire Ondaria has been designed with soft outlines and an even silhouette to blend into any interior. Ondaria is available as an LED luminaire or fitted with standard light sources.

The uniformly illuminated circular luminaire ensures a harmonious ambience in lobbies and foyers, communication areas and lounges as well as corridors and staircases. The luminaire is available in three sizes and can be either recessed, surface-mounted or pendant-mounted.

Despite its strictly geometrical basic design, Ondaria presents itself as a luminaire without any edges. “The luminaire’s concave surface, which is slightly recessed, adds up to a perfectly circular design, creating a special effect of three-dimensionality and depth,” says designer Stefan Ambrozus.

Ambient lighting is provided by its direct light component. Soft uniform light enters the room through the opal diffuser, creating a pleasant atmosphere. Where Ondaria is recessed into the ceiling, its indirect component slightly brightens up the ceiling, visually reducing the luminaire’s height. Ondaria’s soft curves harmoniously blend into a wide variety of interior designs – not only in prestigious areas, but also in offices. This is due to the luminance-reducing optic (LRO optic), available for the medium design size, which allows for perfect glare limitation and light distribution, even at computer workstations. Another asset of Ondaria: the luminaire can be conveniently dimmed and controlled.

Ondaria is available with conventional light sources and also as an LED version with stable white light. Thanks to efficient LED technology, the connected power can be reduced by as much as 58%, providing a pleasantly intermediate light colour of 4000 K and a very high colour rendition quality of Ra > 80. As an LED version, the circular luminaire does not differ in visual terms from the models fitted with fluorescent lamps. Owing to the LED’s long service life of 50,000 hours and stable colour temperature technology, Ondaria LED is practically maintenance-free.
