Square LED recessed light with microprismatic cover PW. Version M84 (625 mm x 625 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 luminous flux is 575 lm. Creation of a deeper spatial effect. For system ceilings with visible support rails. The luminaire body is flush with the ceiling system on the room side. In combination with accessories that can be ordered separately, 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, replicating the 3-dimensional contour of a skylight. The optical system consists of a highly efficient PMMA cover with microprismatics. The microstructured PMMA prism surface of the optical system has an anti-glare effect, is non-yellowing and does not cloud. With symmetrical, limited, wide beam light distribution. Glare rating according to UGR classification (EN 12464-1) <, 19. Suitable for screens according to EN 12464-1 due to limited luminance L = 3000 cd/m2 for beam angles above 65° all around. Harmonious lighting effect due to evenly illuminated light emission. Individual design of the light emission surface (e.g. by printing) and other special solutions available on request. With HCL equipment for controlling the light color using a separate control unit (DT8). LED panels equipped with LEDs in the light color warm white and daylight white. Rated luminous flux 4200 lm, rated power 40 W, maximum luminous efficacy of the luminaire 114 lm/W. Light color variable (warm white - daylight white), correlated color temperature (CCT) variable (2700 K - 6000 K), general color rendering index (CRI) Ra >, 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): 620 mm, 620 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, ta35 °C can also be used without insulation material. Protection class (EN 61140): I, protection type (DIN EN 60529): IP20, protection type on the room side: IP40, shock resistance level according to IEC 62262: IK03, test temperature glow wire test according to IEC 60695-2-11: 650 °C. Weight: 3.7 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, electronic control gear for switching, dimming and controlling the light color using a DALI Device Type 8 capable control device. Control gear in accordance with DALI-2 standard (EN 62386). The control gear is replaceable in accordance with the ecodesign requirements (VO (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. 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 enhanced by variants in the area of the luminous flux package
