EN 62471

With the coming onto the market of high power LED technology, usable both as common and signaling lighting, a confused marketing of poorly performing and unsafe products from a photo-biological viewpoint has taken place.
PERFORMANCE iN LIGHTING therefore as a Group chose to use high power LED from leading brands only.

On an international level a now standard has been fixed: EN62471 (IEC62471). This standard deals in a transversal way with the photo-biological risks of lighting sources and especially of LED devices and products using specific types of discharge lamps and LED light sources.
A classification of GROUPS OF PHOTO-BIOLOGICAL RISKS under which luminaires may fall has been drawn.

The Groups of risks are defined as follows:

Group of Risk Nil:
The luminaires do not pose any photo-biological risks.

Group of Risk 1:
The luminaires do not cause photo-biological damage for the risk is cancelled by the common behavioral reaction of a person to the exposure to a light source.

Group of Risk 2:
The luminaires cannot cause photo-biological damage for the risk is cancelled by instinctive reaction of looking away from a very bright and strong light or from a thermal suffering.

Group of Risk 3:
The luminaires may cause photo-biological damage; risk is high even for a short or instant exposure. It is strongly advised to not use the luminaires for general lighting.
