The harmful effects of UV Blue Light are an issue with our Wellbeing. The World Health Organization (WHO) states that the effects of excessive UV radiation to the eye include photokeratitis and photoconjuctivitis (sunburn of the cornea and eyelids, respectively), pterygium (an opaque growth attached to the cornea), cancer of the conjunctiva and cataracts. At any Kelvin value about 4000K the Blue light level can have an adverse effect on the mental health of the occupants. KraftigLED design Ultra high efficiency LED lighting to maximise savings for customers – we produce lights up to 50% more efficient than other LED lights and with an option of 40% less UV output. We make highly specialised products – for example, our UV-free minimal blue LEDs which allow for elimination of UV filter in UV sensitive manufacturing. These products are in use with some of the world’s largest pharmaceutical companies.
