LED linear fixture HRD-ML-WW-W-PT 37072

Integrated linear LED luminaire designed for recessed ceiling installation

The luminaire is constructed from a steel housing and white synthetic material – its design is simple yet robust, with no unnecessary details. The white diffuser with a raster evenly disperses light, while its shape minimizes the “point light” effect – crucial in spaces where glare and uncomfortable shadows must be avoided. An UGR below 17 ensures excellent performance in offices, retail stores, and public areas, preventing eye strain even during prolonged visual tasks.

Light is emitted downward with a color temperature of 3000 K – warm white, eye-friendly, and ideal for daily use. A luminous flux of 2350 lm at a power consumption of 18 W delivers an efficacy of over 131 lm/W – meaning high light output with low energy use. The color rendering index Ra 80 ensures natural color reproduction – products on shelves or documents on desks will appear true to life, not distorted.

Control and Durability

The luminaire supports DALI control, enabling precise dimming and seamless integration with smart building systems. No additional wiring or external drivers are required beyond those already installed in the building. The integrated LED source has a lifespan of 50 000 hours (L90B10), meaning it will still emit over 90% of its initial luminous flux after this period. With a switching cycle rating of ≥30 000 cycles, it remains reliable even under frequent on/off operation – ideal for motion-sensor applications.

Installation and Operating Conditions

Installation is designed for recessed mounting into ceilings – the luminaire fits within the space between joists or suspended ceiling frameworks. Dimensions (595 x 70 x 52 mm) allow easy compatibility with standard grilles or ceiling cassettes. Connection is via a self-clamping terminal block – no threading or screws needed; simply insert wires with cross-sections from 0.5 to 2.5 mm² and secure. The IP20 rating indicates indoor use only – not suitable for damp areas or outdoor environments.

Operating temperature is limited to 5–25°C – typical for offices and retail spaces, but not for unheated warehouses or boiler rooms. A minimum clearance of 0.5 m from objects is required during installation – ensure this distance is maintained above furniture or shelving units.

A 5-year warranty confirms production stability and component quality. There are no “golden LEDs” or marketing hype – only proven SMD LED technology with color consistency ≤6 SDCM: light output remains uniform over time and across luminaires in the same space.
