The fluorescence becomes noticeable at a level of about 5%, and is strong by about 10-15%. Low-energy light bulbs contain a little europium to give a more natural light, by balancing the blue (cold) light with a little red (warm) light. What this means in practice is that light of one colour can be return as another colour. Scorpions fluoresce or glow under ultra-violate (UV) light turning a teal green so they are easy to find with the aid of a Black light during the night.
