I bet most pople thought that UV light is just used to kill bacteria or check for past blood stain....but in real life it is also use to be use in the dark in low light condition
Pink doesn't show up as bright as yellow or orange(must be being overlap by the paper colour)
To show that i'm not using normal light
Yellow highlight show up best(good for studying but if u are not sheild form the hazard light u might get a headache)
Symbols which only show up when under UV light which are use to detect fake money
This is using UV LED
