ISR300-PSL Luminaire Blue Light Hazard Spectroradiometer

  • ISR300-PSL PSL Spectroradiometer
  • ISR300-PSL-ALIGN Photobiological alignment tool
  • ISR300-PSL Example Measurement Set-up

CE marking of luminaires against the EU low voltage directive 2014/35/EU requires implementation of EN 60598-1 according to which blue light hazard should be assessed with reference to IEC TR 6278.

The ISR300-PSL offers the luminaire manufacturer the most reliable and accurate direct assessment of blue light hazard, devoid of overly conservative assessment results caused by employing an approach based on calculation and estimation.
