Series SIW-HB/ST

The luminaires of the SIW-HB/ST series are  a powerful light source, providing excellent lighting characteristics of the work surface. The LED high bay luminaires of this series successfully replace the conventional  powerful luminaires of the "bell" type.
By using specialized lenses for directional illumination, a high level of uniformity is achieved in the different production areas.
The luminaires can be fixed directly to the ceiling, grills, metal beams,rope or "hanging assembly" according to the specific project. Luminaires have a long life cycle without maintenance costs.

They can operate at extremely high ambient temperatures up to 70°C without forcibly reducing power or cooling.
