Lasers are not toys - not even for adults. Due to their extremely concentrated and therefore high-energy beams, they pose a considerable risk to eyes, skin and objects, which can lead to damage even in the event of indirect contact. Lasers may therefore only be operated in the presence of certified specialist personnel who have been trained in their safe use. With this detailed article on the subject of lasers, we would like to prevent you from switching off the light for yourself or other people. We also explain why classic DMX controllers such as DMXControl (3) are not the best choice.
