As LEDs reach higher intensities and are used in new applications (like automotive headlights, projectors, and horticulture), understanding and mitigating potential photobiological risks is paramount. International standards (like IEC 62471) classify lighting products into risk groups based on potential hazards to the eye and skin from ultraviolet, blue light, and thermal radiation. Reputable manufacturers are now conducting rigorous testing and providing detailed photobiological safety reports. For consumers and specifiers, looking for products that are classified in the exempt or low-risk Group (RG0 or RG1) is becoming important, especially for lighting used in close proximity, like task lights or children’s lamps. This trend reflects the industry’s maturation and responsibility in ensuring that powerful new light sources are safe for human exposure under all intended conditions of use.
