The NiteCore MH27UV is great for multi-functional use. The Cree XP-L HI V3 LED light namely provides even, white light with a focused beam. As such you light up a distance of 462 meters.

With the blue light you can easily find traces of blood. Great when hunting or for law enforcement.
The UV light makes this flashlight really unique. It ensures that everything that contains phosphorus will become visible. When using an ultra-violet light phosphorus absorbs the energy and turns it into visible light. As such you can, for instance, see the authenticity of identity cards, banknotes, gems and minerals. But you can also light up blood, urine and saliva. As such this unique flashlight is also great for forensic research and search ops.
Do, however, keep this in mind: When using the UV light mode you should never point it at your eyes. If you do, you could permanently damage your eyes.
