Decorative rectangular surface-mounted LED luminaire. It features a flat seamless frame with a powder-coated extruded aluminum profile and a powder-coated sheet steel cover. The luminaire provides direct light emission through a diffuser made of non-yellowing opal plastic (PMMA) and indirect light emission via a flush diffuser made of satinized plastic. LED backlight technology ensures homogeneous illumination across the entire light-emitting surface, with direct light emission at 60% and indirect at 40%. It is suitable for ceiling and wall surface mounting, and installation is simple thanks to the plug-and-play connector system. The integrated control gear is DALI dimmable and suitable for through-wiring. Additionally, it includes Casambi smart+free Bluetooth control for wireless networking and operation via Android or iOS devices, with a free app available for download.
