You take a naturally perfect shape like the circle and fill it with astonishingly even light....

the TRIONA recessed luminaire is a lighting tool that lives up to its name by setting new standards in three respects at the same time: visual function, biological effect and emotional light quality.

Ideal for use as part of a Human Centric Lighting (HCL) concept, the series includes versions with tunable white technology. This also makes it possible to generate dynamic lighting, with infinitely variable colour temperature and brightness, simulating the natural course of daylight. This light-induced support for the human circadian rhythm has been proven to have a positive effect on people’s wellbeing and performance. People living in retirement homes or hospitals can benefit in particular from this biological effect, as well as those in offices, conference rooms and classrooms.

In addition, TRIONA in itself generates extremely homogeneous, glare-free, powerful and yet soft light. This is thanks to the RZB SIDELITE® technology, which uses lateral light emission for the rimless illumination of the luminaire body. The series includes versions, which also emit indirect light through the top of the luminaire – ensuring impressive visual and design effects. Despite the additional light emission area, the sizeable top surface of the luminaire does not have any edges or depressions worth mentioning or any visible screws and is therefore quick and easy to clean.

The proportions of the luminaire, which comes in three different diameters, are also remarkable: the high-quality aluminium profile of the housing measures – for a luminaire diameter of up to a metre! – just 50mm, leaving the most space possible in the diffuser for light emission and effect.

Various diffuser versions, including a microprismatic version with UGR ≤ 19 that is suitable for computer workstations, also expand TRIONA’s potential for different applications. The 680mm version of the luminaire can even be enhanced with an elaborately crafted Ferro Murano glass insert, turning it into a unique and precious piece.

Three colours are available for the powder-coated housing. Special colours can also be made for further individualisation. TRIONA is suitable for ceiling and wall installation and is also available as a pendant version.
