Series SIW

The luminaires of the SIW series have  very high efficiency ensuring  powerful light emission with excellent lighting characteristics of the terrain. The luminaires of the SIW series are successful substitute of the traditional powerful luminaires of the "bell" type.The specific design provides very good protection of the illuminating surface from direct hittings during the working process. By using special optics for indoor directional lighting, high uniformity in the various production areas is achieved.The luminaires in this series can be used to illuminate different production areas with significant height, as factories, warehouses and storage terminals.

Specifications:

  • Worldwide powered;
  • Active Power Factor Corrections (PFC);
  • Optics of specialized lenses for indoor directional lighting;
  • High quality area illumination;
  • Ergonomical light - close to natural light;
  • High energy efficiency;
  • Long lifetime;
  • No maintenance coast;
  • Ecological - mercury and lead free.
