Design and operation

The luminaire is made as a hermetic, closed structure in which we can separate three main components:

  • power supply unit – consisting of a body made of die-cast aluminum protected by a paint coating
  • lighting unit – consisting of a lampshade made of polycarbonate with a built-in LED panel;
  • cover assembly – cable gland equipped with a terminal block and a mounting bracket.


As standard, the luminaire is adapted for hanging mounting, e.g. on a rope or chain. Optionally luminaire can be mounted with additional accessories,  for example to the surface of a wall, pipe/mast. As standard, the
luminaire is equipped with one M20x1.5 cable gland (seal range from 6.5mm to 11.9mm, nickel-plated brass) and a blind hole Ø20, to which an additional cable gland can be mounted. On request, it is possible to install other cable gland and / or make holes of different diameter


  • solid, compact structure,
  • simple, easy and quick installation,
  • high resistance to industrial corrosive environment, very high luminous effciency,
  • high-quality power supply and LED diodes,
  • resistant to UV radiation.
