Light and Lighting

Conventional LED lights do not present a health risk if used properly. This also applies to sensitive populations such as children or people who have very clear eye lenses.

LED Lamps

LED Lampen

LED lamps or LED light sources are suitable for energy-efficient indoor and outdoor lighting. They are an alternative to energy-saving and halogen lamps. For technical reasons, LED lights cannot produce white light. They do, however, emit yellowish and blue light which, when mixed together, produce white light. Since blue light poses a risk to the retina of the eye above a certain intensity and irradiation time, lights must comply with the blue light hazard limit. This limit is reached after varying irradiation times, depending on the intensity of the blue light.
