Within this we can distinguish three ranges UVA, UVB, UVC as they move away from visible light and their wavelength is reduced.Īlthough the type of light generated is mainly UVA, which is closest to visible light and carries less energy, some light in the UVB range may be radiated and therefore has to be filtered appropriately. Black light safetyĪs we have already mentioned, black light is nothing more than ultraviolet radiation. In addition to infections, as indicated above, it can be used to detect other types of medical problems such as tuberous sclerosis.
