Square LED recessed luminaire with microprismatic cover PW. Version M52 (312.5 mm x 312.5 mm). The luminaire 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 luminous flux is 475 lm. Creation of a deeper spatial effect. Luminaires only suitable for sawn ceilings, mounting accessories included in delivery. The optical system consists of a highly efficient PMMA cover with microprismatics. The microstructured PMMA prism surface of the optical system has a glare-reducing effect, is non-yellowing and does not cloud. With symmetrical, wide beam light distribution. Glare rating according to UGR classification (EN 12464-1) 80. Color location tolerance (initial MacAdam) = 3 SDCM. 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. Surface coated white (RAL 9016). Luminaire dimensions (L x W x H): 308 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. Luminaire can be covered with insulation material at ta 25 °C, can also be used at ta35 °C without insulation material. Protection class (EN 61140): II, protection type (DIN EN 60529): IP20, protection type on the room side: IP40, shock resistance according to IEC 62262: IK03, test temperature glow wire test according to IEC 60695-2-11: 650 °C. Weight: 1.3 kg. Reverse polarity protected quick connection with mains forwarding 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, switchable. The operating device is replaceable in accordance with the ecodesign requirements (VO (EU) 2019/2020). Operating device is idle-proof and protected against incorrect connection, short circuits, overload and overtemperature. Output ripple of the control gear = 4% for effective control of the LED system and flicker-free light. ENEC certification by an independent testing center is in preparation. 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 variety of applications of the product range 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. Luminaire 10 years, spare parts (LED module, control gear,optical system) 15 years after the invoice date, subject to reasonable changes in the interests of progress.
