The Trilux SFlow D2-L MRWD LED4000-840 ETDD 03 is an LED surface-mounted luminaire for single or light strip applications, specifically designed for ceiling mounting. The product is suitable for use in offices, administrative buildings, retail environments, and other indoor spaces where uniform, area-wide illumination with high visual comfort is required. The luminaire features an optical system in Micro-Reflector-Technology (MRWD), consisting of highly efficient, white-polished reflector chambers made of plastic. These are combined with a diffuser panel to create a homogeneous light pattern. An additional clear cover lens provides a flush finish on the room side and protects the LED elements. Light extraction occurs discreetly laterally along the entire length of the luminaire, resulting in a lambertian luminous intensity distribution that ensures uniform and disturbance-free illumination.

Applications

The luminaire is primarily intended for mounting on flat ceilings. For suspended mounting, the accessory ZS1P 2000 is available. The application is for indoor environments with an ambient temperature between -20 °C and 25 °C. The luminaire is not intended for outdoor use or in damp rooms, as the protection rating IP20 does not provide protection against water or dust.

Functions and Equipment in Detail

The LED system and optical system are inserted tool-free into the luminaire body as an assembly. During installation, the assembly is secured against falling using a steel wire. The light source is replaceable according to Ecodesign requirements (EU Regulation (EU) 2019/2020), as is the ballast. The luminaire features an electronic ballast that is digitally dimmable (DALI) and complies with the DALI-2 standard (EN 62386). Via DALI control terminals, the luminaire can be switched and dimmed using touch dimming (Touch DIM). The light colour is neutral white with a correlated colour temperature (CCT) of 4000 K; the general colour rendering index (CRI) is Ra > 80. The colour locus tolerance is 3 SDCM (initial MacAdam). The rated luminous flux is 4000 lm at a rated power of 28 W, corresponding to a maximum luminous efficacy of 143 lm/W. The average rated lifetime (L80 at 25 °C) is 50,000 hours.

Technology Explained Simply

The Micro-Reflector-Technology (MRWD) ensures precise light guidance and minimizes glare. The white-polished reflector chambers efficiently and evenly reflect the light. The diffuser panel further distributes the light to ensure homogeneous illumination. The clear cover lens protects the LED elements and provides a clean optical finish. The lambertian luminous intensity distribution means that light is emitted uniformly in all directions, ensuring even and disturbance-free illumination. DALI control enables central switching and dimming via a network, allowing light intensity to be adjusted according to specific needs. Flicker-free operation (Pst LM = 1.0 at full load) and low stroboscopic effect (SVM = 0.4 at full load) ensure pleasant and eye-friendly lighting.

Compatibility and Accessories

The luminaire is compatible with separate accessories for suspended ceilings (SFlow ZBP L2) and suspended mounting (ZS1P 2000). Electrical connections between assemblies are made automatically. The luminaire is monitoring ready (MOR) and provides luminaire data for monitoring or predictive maintenance. It is compatible with TRILUX Monitoring Services. Certification is in accordance with applicable EU directives and the Product Safety Act; CE marking is present. Additionally, the luminaire is ENEC certified.

Installation and Mounting

Mounting is done to the ceiling, with the assembly inserted tool-free into the luminaire body. Electrical connections are made via plug-in terminals on the mains side. The assembly is secured against falling using a steel wire during installation. The luminaire is designed for indoor use; the protection rating IP20 protects against finger contact, but not against water or dust. The impact resistance is IK03, indicating low protection against mechanical impacts. The glow wire test temperature is 650 °C.

Operational Advantages

The luminaire offers a high luminous efficacy of 143 lm/W and a long service life of 50,000 hours (L80). The replaceable components (LED module, ballast, optical system) enable long-term use and maintenance. DALI control and Touch-DIM functionality offer flexibility in light control. Monitoring capability (MOR) enables luminaire monitoring and predictive maintenance. Spare parts are available for 15 years after the invoice date, and the luminaire itself for 10 years. The surface is silver-grey coated (similar to RAL 9006), and the luminaire body is made of sheet steel. Dimensions are 1413 mm (L) × 84 mm (W) × 45 mm (H), and the weight is 4.1 kg.

Protection Rating, Protection Class, and Environmental Conditions

The protection rating IP20 protects against finger contact, but not against water or dust. Protection class I requires a protective earth connection. Impact resistance is IK03. The permissible ambient temperature range is between -20 °C and 25 °C. The glow wire test temperature is 650 °C.

Certification and Conformity

The luminaire meets the essential requirements of applicable EU directives and the Product Safety Act. CE marking is present. Additionally, the luminaire is independently tested and ENEC certified. Ecodesign requirements (EU Regulation (EU) 2019/2020) are fulfilled for both the light source and the ballast.

Availability of Spare Parts

Spare parts such as the LED module, ballast, and optical system are available for 15 years after the invoice date. The luminaire itself is available for 10 years. Availability is subject to reasonable changes that serve technological progress.
