SA Rhea.

Our ‘Semi-Autonomous’ Rhea LED circular luminaire uses integrated sensors to automatically recognise when and where light is needed. This enables energy savings of 60-80% compared to conventional LED round luminaires. The Rhea does not require external components such as central motion detectors, as the intelligent control system is integrated directly into the luminaire. This not only makes the installation of the SA Rhea cost-efficient, but also reduces maintenance costs in the long term. For applications where connected lighting is preferred, the NOMUS Rhea offers a suitable alternative.

Thanks to its energy-efficient technology, the SA Rhea is ideal for circulation areas such as stairwells, corridors, entrance areas and covered outdoor areas such as house entrances thanks to its IP54 splash water protection. In addition to circulation areas and ancillary areas, Rhea’s design and lighting properties make it suitable for communal areas, canteens, cafeterias and sanitary facilities.

Rhea can be designed in over 100 different versions thanks to numerous customisation options, such as the switchable light colour, switchable backlight or adjustable output, the decorative ring, the pendant or the emergency lighting kit with integrated battery and self-test function. In the pendant version, for example, the Rhea creates a unique sense of space, making it particularly suitable for entrance areas. The reduced operating time thanks to the intelligent control system and the high quality also significantly extend the service life of the SA Rhea compared to conventional LED round luminaires.
