Square LED recessed luminaire with translucent cover panel DW. Version M73 (600 mm x 600 mm). Version with increased protection class IP54 on the room side. 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 lighting mode, the luminaire luminous flux is 575 lm. Creation of a deeper spatial effect. Complies with DIN 10500. The luminaires are suitable for use in HACCP, IFS Version 6 and/or BRC Global Standard Food Version 7 certified companies in the food and beverage industry. Suitable for use in HACCP, IFS Version 6 and/or BRC Global Standard Food Version 7 certified companies (DIN 10500). For system ceilings with visible support rails. The luminaire body is flush with the ceiling system on the room side. The Sky frame, which is optionally available as an accessory, creates a spatial, atmospheric depth effect in the classic, flat modular ceiling, simulating the 3-dimensional contour of a skylight. The optical system consists of a translucent, non-yellowing PMMA cover with a high degree of transmission. The surface of the cover is smooth and free of visible, microprismatic structures. With deep-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 in white (RAL 9016). The narrow flank profile is flush with the support rail. 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, ta35 °C can also be used without insulation material. Protection class (EN 61140): II, protection type (DIN EN 60529): IP20, protection type on the room side: IP54, shock resistance level according to IEC 62262: IK03, test temperature glow wire test according to IEC 60695-2-11: 650 °C. Weight: 3.4 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 control gear, switchable. The control gear is replaceable in accordance with the ecodesign requirements (Regulation (EU) 2019/2020). Control gear is idle-proof and protected against incorrect connection, short circuit, overload and overtemperature. Output ripple of the control gear = 4% for effective control of the LED system and flicker-free light. The product meets the basic requirements of the applicable EU directives and the Product Safety Act and bears the CE marking.In addition, the luminaire is ENEC-certified by an independent testing center. 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.
