LED lamps or LED lighting systems are suitable for energy-efficient interior and exterior lighting. They are an alternative to energy-saving and halogen lamps.
For technical reasons LED lamps cannot produce white light, but rather emit yellow and blue light components that when mixed together result in white light. As blue light, above a certain intensity and irradiation time, represents a risk to the retina of the eye, the lamps have to meet the limit value for blue light exposure. This limit value is attained after a longer or shorter irradiation time depending on the intensity of the blue light component.
Commercial LED lamps represent no health risk when used correctly. This is also true for vulnerable population groups, such as children or persons, who have very clear, synthetic eye lenses or none at all.
Lamps are classified into the following risk groups. Lamps in the "exempt group" are risk-free even with unlimited use. Lamps in the risk groups 1 and 2 are risk-free for a limited period of use, whereas lamps of risk group 3 exhibit a high risk even for very short periods of use.
