Counterfeit Money & Security Marker Detector Replacement Light Bulb.

 2 Pin T5 fitting UV Blacklight.

Brand New

The bulbs are approximately 150mm high (135mm excluding pins) by 16mm wide.

These bulbs emit UV and are intended for use in counterfeit note detectors.

 The UV light is  for authentication, e.g. security markings on currency & credit cards, certificates of authenticity on software packaging, as well as special inks used by security marking pens; non-destructive testing of materials and reading of otherwise illegible papyri and ancient manuscripts; analysing minerals and gems, and other detective work including authentication of various collectibles - Materials may look the same under visible light, but fluoresce to different degrees under ultraviolet light. 

In forensics, black lights are required to observe fluorescence of substances and are used as an investigative tool at the crime scene to locate and identifying body fluids and changes brought on by decomposition.
