Nitecore P20i UV Overview

Combining powerful output, long runtime, and tactical features with an ultraviolet light, the Nitecore P20i UV Rechargeable Tactical LED Flashlight will meet the needs of professionals in a wide range of disciplines. Its four UV LEDs are useful for currency and document inspection, forensic investigation, mine exploitation, and gemological appraisal.

The light's reflector is engineered with crystal coating and precision digital optics technologies for a long throw. Its strike bezel has high-hardness silicone nitride ceramic tips, which make the bezel more effective in breaking glass or self-defense but less likely to damage the inside of a pocket or pack. Built for durability, the light features an aluminum housing with a Type III hard-anodized black finish, an anti-roll ring, and diamond-pattern knurling for a good grip. Advanced Temperature Control circuitry guards against overheating. O-ring sealed and IP68-rated, the light is submersible and impact rersistant to to 6.6'.

Nitecore P20i UV Reviews

Good LED. Poor UV

By Michael

Overall good LED flashlight with multi modes. However if you want good UV this light is a failure. Not 365 advertised. Barely registers anything in the UV mode. Could be 395 instead but can’t verify.

Good light but with one complaint.

While overall I like the P20i, I have one complaint with Nitecore stating on the literature I read about this light that, it's powered by a 21700 battery. Problem is that it isn't until you receive the light, that you realize the 21700 battery it uses is not a standard 21700 battery. Its actually a NL2140 proprietary battery that is quite a bit longer and more expensive than a standard 21700 battery and, will not fit in most stand alone chargers. I would have given it 5 stars if it weren't for this.
