flashlight 1. Chargingf luorescent materials: UV torches will
charge "glow in the dark" materials almost instantly. Useful for
night fishing, camping etc. 2. Document and forgery analysis: UV
light can sometimes show alterations and erasures to documents.
Alterations or changes will sometimes become directly visible when
illuminated by UV light. 3. Crowd and access control: Often access
to events is controlled using an invisible mark on a hand or card
that when illuminated with UV becomes visible (fluoresces). Instead
of carrying around heavy and hot black lights, this UV LED penlight
can be slipped into a pocket. 4. Crime scene inspection: Some bodily
fluids will fluoresce under UV light. Law enforcement agencies use
to inspect crime scenes to detect blood + other bodily fluids and
many other things that are not visible to the human eye under normal
light conditions. Some people even inspect their hotel sheets before
use to see if the beds have been changed. Arson investigators use UV
to search for the presence of accelerants.
