Nitecore Tube Rechargeable UV LED Keylight

See The Unseen!

One of the most compact ultraviolet lights on the market, the Nitecore Tube Rechargeable UV LED Keylight is a potent combination of power and portability. Equipped with a 365 Nanometer Ultraviolet LED, the keylight delivers an intense 500 milliwatt UV output that can run for up to an hour on a single charge. Ideal for checking currency and identity cards for counterfeits, this handy-sized light is an effortless addition to any keychain, making it as convenient to carry as it is effective to use. And with its sturdy polycarbonate body, it can withstand the bumps and bruises that come with regular use.

Internally Rechargeable

Changing batteries for such a compact light could get monotonous and expensive. To avoid the frustration and the expense, the Tube UV is designed with an integrated intelligent Li-Ion battery charging circuit with a micro-USB charging port for quick and easy recharging. To display the charging progress, the keylight features a blue power indicator light that glows when the light is charging and shuts off once charging is complete. Between its compact size, its tough body, and its practical rechargeable battery, the Nitecore Tube UV is the most convenient UV light on the market today!

Compact, Convenient little UV light.
August 26, 2016
I bought this little device to keep on my key chain...I live in the desert southwest and tent camp in the local parks a lot. I have had several close encounters with bark scorpions, so having a UV light source when I'm crawling in and out of my tent after dark was a must. The little bastards glow yellowish/green when you shine UV light on them and it's a nice heads up. I have owned several Nitecore lights and have never had any issues with them. The added convenience of being able to recharge the light with the same mini USB cable that I charge my phone with...Is great and it's water resistant. Battery life is about 2 hours of constant use and several weeks with occasional use. It's a great little EDC light, with decent throw for the LED size. Buy with confidence...It get's the job done.
  • Rechargeable with mini USB.
  • Water Resistant.
  • Fits on your key chain.
  • Scorpion finder!
  • Doesn't kill scorpions.

Didn't last long.

I didn't use this much and, after sitting for a few months, didn't come on when I pressed the On Switch.
I figured that it needed a charge, and the blue indicator comes on, but it still doesn't work.

very small UV light source

This light is amazingly small for a rechargeable. The output is not very strong but reliable. Good for small item viewing only.
