The Trilux SNS RC7 HRXFL-22 26-840 ETDD 01 is a compact LED downlight with a round design, specifically designed for installation in sawn ceiling openings. It features an installation frame that enables tool-free mounting using quick-mount clamps. The luminaire is suitable for use in offices, corridors, foyers, conference rooms, retail areas, and waiting zones, particularly at workstations with display devices. The light distribution is symmetrical with a half-value angle of 80°, corresponding to an Extreme Wide Flood characteristic. Light control is achieved through a diffuser and a high-gloss coated plastic reflector, ensuring uniform illumination and limiting direct glare in accordance with UGR 22.

Applications
This downlight is designed for indoor environments with ambient temperatures ranging from -20 °C to +25 °C. It is particularly suitable for rooms where high light quality and a comfortable lighting environment are required. The room-side protection rating IP54 protects against dust and splashing water, enabling use in slightly damp areas such as entrance areas or corridors. Protection class II and IP20 on the device side ensure safe operation indoors.

Functions and Equipment in Detail
The luminaire features an LED module with a neutral white light colour (CCT 4000 K) and a colour rendering index Ra = 80, ensuring good colour rendering. The colour locus tolerance is 2 to 3 SDCM, corresponding to very high colour consistency. The luminous efficacy is 124 to 138 lm/W, with a luminous flux of 2,600 lm. The connected power varies between 18.8 W and 21.0 W, depending on the source. The average lifetime is L90 (tq 25 °C) = 50,000 to 100,000 hours and L80 (tq 25 °C) = 100,000 hours. The light source and power supply unit are replaceable in accordance with Ecodesign requirements (EU Regulation (EU) 2019/2020).

Technology Explained Simply
The power supply unit is digitally dimmable and complies with the DALI-2 standard (EN 62386). The luminaire can be switched and dimmed via DALI control terminals using touch dimming (Touch DIM), with a dimming range of 1 to 100 %. Power supply is via a 5-pole connection terminal up to 2.5 mm², supplemented by a separate 5-pole power feed-through box. The housing and heat sink are made of aluminium die-cast, ensuring efficient heat dissipation. The impact resistance is IK06, and the filament test was carried out at 850 °C, confirming thermal stability. The luminaire is silicone-free, which is advantageous during processing and use in sensitive environments.

Compatibility and Accessories
The luminaire is Live-Link ready, enabling integration into intelligent lighting systems. Certification is in accordance with applicable EU directives and the Product Safety Act, and the luminaire carries the CE marking as well as ENEC certification by an independent testing body.

Installation and Mounting
The installation depth must be at least 127 mm, and the luminaire height is 130 mm. The ceiling cutout size is Ø 210 mm. Tool-free mounting is achieved via quick-mount clamps, speeding up and simplifying installation. The connection terminal enables a secure and reliable electrical connection.

Operational Advantages
The high luminous efficacy, long service life, and dimmable function ensure energy-efficient and flexible use. The replaceability of the light source and power supply unit reduces maintenance costs. The Trilux replacement guarantee ensures availability of the luminaire for 10 years and of spare parts (LED module, power supply unit, optical system) for 15 years after the invoice date, with reasonable changes that serve progress reserved.
