Class 1 products are safe to eyes and skin under reasonably predictable conditions. This implicates a direct observation of the light beam by means of optical instruments. When driven with higher continuous forward current, (up to 1 A), this product should be classified as LED product Class 1M, according to standard IEC 60825-1:A2. Class 1M products are safe to eyes and skin under normal conditions, including when users view the light beam directly. Class 1M products produce either a highly divergent beam or a large diameter beam. Therefore only a small part of the whole light beam can enter the eye. However, such optical products can be harmful to the retina if the beam is viewed using magnifying optical instruments. Therefore, users should not incorporate optics that could concentrate the output into the eyes. If intended to operate at very high continuous current (>1 A), this product has to be (potentially) classified as Class 3B LED. Class 3B LEDs may have sufficient power to cause an eye injury, both from the direct beam and from reflections,so these products are therefore considered hazardous to the eye. However, the extent and severity of any eye injury arising from an exposure to the light beam of a Class 3B product will depend upon several factors including the radiant power entering the eye and the duration of the exposure. Nontheless, adequate precautions should be taken to avoid direct or indirect viewing into the beam. *Note: Safety classification of an optical component mainly depends on the intended application and the way the component is being used. Furthermore, all statements made to classification are based on calculations and are only valid for this LED “as it is”, and at continuous operation. Using pulsed current or altering the light beam with additional optics may lead to different safety classifications. Therefore these remarks should be taken as recommendation and guideline only.
