The compact, only 70 mm high recessed downlights of the Lunis R® family are characterised by a combination of a high-performance, energy-efficient T16 circular fluorescent lamp and various optical accessories. A special recessed module in the centre of the luminaire accommodates numerous additional components such as loudspeakers, air-handling elements, coloured LED elements or emergency light. The recessed downlight in addition to general room lighting offers targeted accent lighting for retail, office or public areas. Individualised in this way, Lunis R® for ceiling recessing significantly contributes to a harmonious and calm ceiling appearance.

• minimal influence of ceiling appearance due to compact design
• decorative colour effects of indirect light component via coloured filter segments
• especially flat construction with height 70 mm
• high luminaire light output ratio (C-louvre)
• with the ceiling recessed version, additional functions can be integrated into the central module (sensors, air-handling, acoustics)
• tool-free mounting of optical enclosure

Modular construction of circular downlight, various optical enclosures and a large selection of central modules:
Housing and reflector for circular downlight of ultra-pure aluminium (Al99.98%), metallic grey (RAL 9006) or pure white (RAL 9010) housing |
