Square LED recessed light with microprismatic cover PW. Version M73 (600 mm x 600 mm). Light with Active equipment for controlling the light color using a separate control unit. Creates a deeper spatial effect. LED recessed light for system ceilings with visible support rails. The light body is flush with the ceiling system on the room side. 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 deep-wide beam 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. Luminaire body made of extruded aluminum profile. Surface coated white (RAL 9016). Weight: 3.6 kg. 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, can also be used without insulation material at ta35 °C. 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: IK02, test temperature glow wire test according to IEC 60695-2-11: 650 °C. 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 operating device for switching, dimming and controlling the light color using a DALI Device Type 8 capable control device. Operating device according to DALI-2 standard (EN 62386). Operating device is idle-proof and protected against incorrect connection, short circuit, overload and overtemperature. The operating device is replaceable. 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 law and bears the CE mark. 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 575 lm. 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 575 lm. The luminaire is part of a range of recessed, surface-mounted and suspended luminaires that are coordinated in appearance. The range of applications of the product range is made possible by variants in the area of luminous flux packages,Light distribution curves and protection classes are additionally highlighted. On request, the basic range can be expanded to include project-specific luminaire features.
