because of the coating on black lights they filter out most visible light and emit heavy amounts of infrared and UV-A light. Infrared light is not a problem for leos, since they cant see it. However UV-A light isnt good for leos, as it can hurt their eyes, almost like a sunburn. The reason a black lights UV-A is harmful is because it is undiluted. A common type of example woulf be using water. Lets pretend boiling water is UV-A, and ice water is the rest of the light spectrum. Mix them both and you have warm water, which wont burn your hands, but 'filter out' the ice water and your hands get burned by the boiling water.
