Design and operation

  • body – aluminum alloy,
  • pressure ring – aluminum alloy,
  • tempered glass,
  • LED light module,
  • power supply with an integrated 3×1.0mm2 power cord (length 300mm),
    luminous flux adjustment via 1-10V, DALI according to versions,
    mounting eyelet,

Optionally, the luminaire can be:

  • equipped with a connection chamber (ICB variant) with two openings for inserting power cables. The holes are equipped with M20, M25 cable gland or can be blind,
  • equipped with an industrial power supply (IPS variant),
  • adapted to work at elevated temperatures (HT variant),
  • led driver is separated from the light unit (SD variant).


  • robust and compact design,
  • quick, simple and easy installation,
  • high resistance to a corrosive industrial environment, very high luminous efficacy,
  • high-quality power supply unit and LEDs,
  • UV-resistant.
