LED linear luminaire HR-LL-WW-B-PT 37037

Recessed linear ceiling luminaire with integrated LED

The luminaire is designed for installation in indoor ceilings – ideal for offices, training rooms, corridors, or commercial spaces requiring a uniform, reliable lighting line. The integrated LED light source ensures constant brightness without the need for bulb replacement.

Light is emitted downwards with a 60° angle in both planes – the distribution is even, without sharp shadows. The light color is warm white (3000 K), with a high color rendering index (Ra 80), making colors in the room natural and distinct. Color uniformity does not exceed 6 SDCM – differences between luminaires in the same arrangement are invisible.

The diffuser with a grille and black finish absorbs unwanted reflections, while UGR below 15 guarantees a low level of glare – important for long-term work at a desk or monitor. Luminous efficacy is 115 lm/W, which, with a flux of 2650 lm, indicates efficiency typical of modern LED solutions.

The housing made of steel and plastic ensures durability and resistance to mechanical damage. The diffuser material is also plastic – resistance to yellowing and deformation under temperature influence is ensured by the design. The luminaire has protection class I – it requires connection to a protective conductor.

It does not support dimmers – it operates only at full power. Operation is possible at 220–240 V AC, 50 Hz frequency. Connection wires can have a cross-section from 1.5 to 2.5 mm² – a self-clamping terminal block connection facilitates installation even in limited space.

Operating temperature is limited to the range of 5–25°C – it is not suitable for installations in places with extreme thermal conditions. IP20 rating means protection only against touch and large objects – it is not intended for humid or dusty environments.

Durability is 50,000 hours (L90B10), and the number of on/off cycles exceeds 30,000 – this is not only lifespan but also resistance to frequent switching. Warranty is 5 years.

Dimensions: length 875 mm, width 70 mm, height 52 mm. Minimum distance from the illuminated object is 0.5 m – sufficient for most standard ceilings.
