Square LED recessed light with microprismatic cover PW-X. Version M84 (625 mm x 625 mm). Unique lighting effect due to an internal light gap and flatly illuminated light output. Internal light gap can be individually designed according to customer requirements. 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 light 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, the 3-dimensional contour of a skylight is reproduced. 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, does not yellow 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 round. 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. Luminaire luminous flux and light color fixed. Rated luminous flux 4200 lm, rated power 31 W, maximum luminous efficacy of luminaire 135 lm/W. Light color neutral white, correlated color temperature (CCT) 4000 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): II, 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: 3.5 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 allows the control gear to be removed separately for pre-assembly, the other components of the luminaire remain protected until final assembly. With external control gear, digitally dimmable (DALI). Control gear 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 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. ENEC certification by an independent testing center is in preparation. 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 marking. The luminaire is part of a range of recessed, surface-mounted and suspended luminaires, which in appearance
