Rectangular LED recessed light with microprismatic cover PW. Version M57 (312.5 mm x 1250 mm). The light can optionally be equipped with an emergency lighting system for ceiling installation with an emergency lighting operating time of 3 hours. In emergency light mode, the luminaire's luminous flux is 500 lm. Creation of a deeper spatial effect. For system ceilings with visible support rails. The light body is flush with the ceiling system on the room side. In combination with accessories that can be ordered separately, it is suitable for sawn ceiling openings and for flush-mounted installation. The sky frame, which is optionally available as an accessory, creates a spatial atmosphere of depth in the classic, flat modular ceiling, simulating the 3-dimensional contour of a skylight. The optical system consists of a highly efficient PMMA cover with microprismatics. PW (prismatic wide). The microstructured PMMA prism surface of the optical system has a glare-reducing effect, is non-yellowing and does not cloud. With a deep-wide beam of light intensity distribution. Glare rating according to UGR classification (EN 12464-1) 80. Average rated service life L80(tq 25 °C) = 100,000 h, average rated service life L90(tq 25 °C) = 50,000 h. The light source is replaceable in accordance with the ecodesign requirements (Regulation (EU) 2019/2020). Luminaire body made of extruded aluminum profile. Frame powder-coated white (RAL 9016). Luminaire dimensions (L x W x H): 1245 mm, 308 mm, 22 mm. The all-round edge of the frame profile makes installation easier. The luminaire frame is profiled in 3 dimensions to create a depth effect in the ceiling. The luminaire can be covered with insulation material at ta 25°C, and can also be used without insulation material at ta35 °C. Protection class (EN 61140): II, protection type (DIN EN 60529): IP20, protection type on the room side: IP40, shock resistance level according to IEC 62262: IK03, glow wire test temperature according to IEC 60695-2-11: 650 °C. Weight: 3.6 kg. Reverse polarity protected, quick connection with mains transmission up to Ø 2.5 mm2. Connection of the ballast to the luminaire using a plug connection (plug and play). The packaging concept of the luminaire enables the operating device to be removed separately for pre-assembly, the other components of the luminaire remain protected until final assembly. With external operating device, digitally dimmable (DALI). Operating device in accordance with DALI-2 standard (EN 62386). Luminaire can be switched and dimmed using a touch function via DALI control terminals (Touch DIM). The operating device is replaceable in accordance with the ecodesign requirements (Regulation (EU) 2019/2020). Operating device is idle-proof and protected against incorrect connection, short circuit, overload and overtemperature. Output ripple of the operating device = 4% for effective control of the LED system and flicker-free light. The luminaire can be equipped with the Monitoring ready (MOR) functionality on request.The product meets the basic requirements of the applicable EU directives and the Product Safety Act and bears the CE mark. The luminaire is part of a range of recessed, surface-mounted and suspended luminaires that are coordinated in appearance. The product range's wide range of applications is further underlined by variants in the area of luminous flux packages, light distribution curves and protection classes. On request, the basic range can be expanded to include project-specific luminaire features.
