Solid-state lighting (SSL) is expected to become the most widely used type of light source, promising to bring significant energy savings as it replaces older technologies. However, due to specific spectral characteristics of white light emitting diodes (LEDs), as compared to other artificial sources, some concerns have been raised regarding safety. SSL products should be proven to be at least as safe as the products they intend to replace, and new or unusual conditions of usage should be considered. This paper deals with potential health issues related to LED lighting, with a focus on light flickering and the “blue light hazard”. An overview is given on current studies and latest expert opinions on photobiological safety. Following our measurements, the risk groups of a few consumer LED lamps are determined. We also make recommendations on how to limit the risk through regulation at the EU level. In addition, we have studied the flickering of fifty LED lamps, which were found to have widely varying behaviour (ranging from zero to one hundred per cent flickering). This last result is rather embarrassing because light flicker may cause temporary illness and visual fatigue. It is rather clear that the potential impacts of LED products on human health and well being has to be taken into account seriously before low quality and potentially harmful products submerge the European market.
