The Trilux ArimoFit G2 M57 PW19 52-840 ETDD is a rectangular LED recessed luminaire designed specifically for installation in system ceilings with visible support rails. The product features a micro-prismatic cover PW, enabling a deep-wide light intensity distribution and creating a deep room effect. The luminaire body made of aluminium extruded profile closes flush on the room side with the ceiling system and is equipped with a 3-dimensional profiled frame, creating an atmospheric depth effect in the ceiling area. The cover is made of high-efficiency PMMA material with micro-prismatic structure, which reduces glare, is resistant to yellowing, and shows no clouding. The luminaire is designed for indoor use and offers a protection rating of IP20 (DIN EN 60529) and IP40 on the room side. The impact resistance is IK03, and the filament test according to IEC 60695-2-11 was carried out at a test temperature of 650 °C.

Applications

The luminaire is intended for installation in system ceilings, particularly in rooms with visible support rails. It is suitable for office and administrative spaces, conference rooms, and other indoor areas where uniform, glare-free lighting with a visual depth effect is desired. The luminaire can be combined with optional accessories for sawn ceiling openings and flush-mounted surface mounting. The Sky frame as an accessory creates an optical depth effect reminiscent of a skylight contour.

Functions and Equipment in Detail

The luminaire features an external power supply unit that is digitally dimmable according to the DALI-2 standard (EN 62386). Control is via DALI control terminals with touch function (Touch DIM), enabling switching and dimming of the luminaire. The power supply unit is designed to operate without load and is protected against incorrect connection, short circuit, overload, and overheating. The output ripple is 4 %, ensuring effective control of the LED system and flicker-free light. The light source is replaceable according to Ecodesign requirements (VO (EU) 2019/2020). The power supply unit is also replaceable and meets the same Ecodesign requirements.

Technology Explained Simply

The micro-prismatic cover PW ensures a broad, deep-reaching light distribution, minimizing glare and enabling uniform illumination of the room. The glare evaluation according to UGR classification (EN 12464-1) is 80, representing a good glare rating for office environments. The average rated lifetime is L80(tq 25 °C) = 100,000 hours and L9o(tq 25 °C) = 50,000 hours. The luminaire can optionally be equipped with an emergency lighting system providing 3 hours of operation. In emergency lighting mode, the luminous flux is 500 lm. The luminaire can be covered with insulation material at an ambient temperature of 25 °C; at 35 °C, it can be used without insulation material.

Compatibility and Accessories

The luminaire is part of a range of recessed, surface-mounted, and pendant luminaires that are visually coordinated. The product series offers variants in luminous flux packages, light distribution curves, and protection ratings. Optionally, the luminaire is available with an emergency lighting system and the Sky frame. The Monitoring ready (MOR) functionality can be added upon request. Connection options include a polarity-protected quick connection with mains continuation up to Ø 2.5 mm², as well as a plug-and-play connection for the ballast.

Installation and Mounting

Mounting is facilitated by the surrounding edge of the frame profile. The packaging concept allows for the separate removal of the power supply unit for pre-assembly, while the remaining components remain protected until final installation. The luminaire is designed for installation in system ceilings and can be combined with additional accessories for sawn ceiling openings and flush-mounted surface mounting.

Operational Advantages

The luminaire offers a long service life, glare-free lighting, and flexible control via DALI. The replaceability of the light source and power supply unit supports maintenance and operation throughout the entire service life. The option to equip the luminaire with an emergency lighting system and Monitoring ready (MOR) extends its functionality for demanding applications. The luminaire meets the basic requirements of applicable EU directives and the Product Safety Act and carries the CE marking.
