Which risk group do JUST Normlicht lighting devices belong to?
According to EN 62471: 2008 Paragraph 6.1, risk groups for lighting devices are defined as below:
RG0 (Exceptional Group): No photobiological hazard.
RG1 (Low Risk): No photobiological hazard under normal behavioral limitations.
RG2 (Medium Risk): Does not pose a hazard due to aversion response to bright light or termal discomfort.
RG3 (High Risk): Hazardous even for momentary exposure.
The simulation of CIE daylight illuminants D50 or D65 require a small amount of UV-A to be compliant with the standards.
Therefore JUST Normlicht lighting devices belong to risk group 1 (low risk).
Damage to the eye does not occur, even with fixed gaze in the direction of the light source with limited duration (limited exposure duration).
