To activate optical brighteners in textiles, plastics or paper, the X-IV also has UVA light.

Technical specifications:

  • Ceiling luminaire for a uniformly illuminated work surface approx. 100 x 80 cm, for larger products several luminaires can be mounted side by side
  • Microprismatic UV-transparent light diffusion plate for homogeneous light distribution
  • No reflection of the tubes in shiny samples
  • Two-step illuminance level for all 4 light types: For installation in our light cabin: Level 1> 2000 lx / Level 2> 3000 Lux *
  • For ceiling suspension at a distance of 1.00 m from the work surface: Level 1> 1500 lx / Level 2> 2500 Lux *
  • UVA - light for optical brighteners
  • Ceiling light with 4 suspension eyes for rope / chain suspension, also with screws for ceiling installation (at least 10 cm distance to the ceiling for heat dissipation)
  • Optionally, we offer a set of suspension material, from 2 lights aluminum profiles with suspension material to secure the connection of the lights
  • Housing dimensions 124 x 80 x 16 cm
  • Connection 230 V / 50/60 Hz, protection at least B10 A

The height of the work surface in a standing workplace should be approximately 90 - 100 cm from the floor for visual color matching for persons with a mean height of 175 cm. Depending on the size of the person also higher, so that the 45 ° angle is observed on the samples.
The workstation should be installed in a darkened room or room corner with little extraneous light influencing the light quality of the luminaire.
Above-mentioned Illuminance levels refer to the center of the work surface, depending on the ambient color and wall color or brightness.

Ceiling lights with several types of light are recommended for the following applications:

  • Color sorting of products, spare parts, food
  • Color testing of standards and samples under daylight simulation
  • Metamerism test under TL84 and illuminant A according to norm on color pairs to avoid "color accidents"
  • Additional LED lighting with the same illuminance for advanced metamerism testing
  • For more freedom of movement in the color evaluation


  • Luminaire housing with light diffusion discs
  • All fluorescent lamps
  • Threaded rods with suspension eyes, stainless steel chain, carabiner (without dowel for the ceiling)
  • Power cable, control cable
  • Electronic control unit for wall mounting
  • Control panel for under-counter mounting or for milling in the table top

* The values given for illuminance are so-called maintenance values which are still reached after 1 year of operation or 2000 hours. A tube change after 2500 hours is recommended.

We are pleased to give you advice or assist you in planning larger illuminated areas.
