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. If intended to operate at higher continuous current, 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, so only a small part of the whole light beam can enter the eye. However, these LED 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. *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. We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications.All operating parameters must be validated for each customer application by the customer.
