As with any light source or lamp fixture, LED product must be consistent with the photo-biological safety standard EN62471. This standard defines the characteristics to be respected to avoid health risks in the use of light , mainly for the eyes and skin. As such, the levels of Ultra-violet, infra-red and blue light are measured to precisely define the level of risk to the user. This is a sensitive subject because few laboratories in the world have all the equipment necessary for all the measures specified in the standard EN62471 on all wavelengths recommended. NOVADAY products are classified and certified by DEKRA "Zero risk" within the meaning of the standard , in relation to the recommendations of ANSES.
