Square LED surface-mounted luminaire ArimoFit G2 D PW19 42-840 ET 01/01 with micro-prismatic cover PW19, specifically designed for mounting on ceilings, walls, and soffits in indoor spaces. The optical system, consisting of a highly efficient PMMA cover with micro-prismatic structure, provides a symmetrically limited wide light distribution and reduces glare. The micro-structured surface is resistant to yellowing and does not cloud, ensuring long-term uniform light quality. The glare rating according to UGR classification (EN 12464-1) is 80, guaranteeing excellent visual comfort in work and utility spaces. The color locus tolerance (initial MacAdam) is 3 SDCM, ensuring high color consistency and visual harmony. The luminaire has a nominal service life of L80(tq 25 °C) = 100,000 h and L90(tq 25 °C) = 50,000 h, enabling high reliability and reduced maintenance frequency. The light source and ballast are replaceable according to Ecodesign requirements (EU Regulation (EU) 2019/2020), enhancing sustainability and product lifespan. The surface-mounted luminaire consists of a mounting body with connection unit, quick-connect system, and ballast, as well as a mounted luminaire unit with LED system, cover, quick-connect system, and a 3-dimensional profiled frame. The surface is white-coated (RAL 9016), achieving a modern and uniform appearance. The recessed cutout creates a shadow gap, reducing the perceived overall height. The luminaire is equipped with an electronic, switchable ballast that is resistant to no-load operation and protected against incorrect connection, short circuit, overload, and overheating. The protection class is I, the protection rating is IP40 (dust- and splash-proof, suitable for indoor use), and the impact resistance rating corresponds to IK03. The test temperature in the glow wire test is 650 °C. Dimensions are 607 mm x 607 mm (L x W) with a height of 42 mm; weight is 7.4 kg. The packaging concept allows for separate removal of the ballast for pre-assembly, increasing installation efficiency. The luminaire is part of a coordinated range of recessed, surface-mounted, and pendant luminaires, enabling consistent architectural design in buildings. Project-specific extensions are available upon request. Warranty: luminaire 10 years, spare parts (LED module, ballast, optical system) 15 years from invoice date, subject to reasonable modifications that serve progress.
