Nitecore® TUBE is a tiny USB rechargeable LED light that puts out an impressive 55 lumens. The brightness is infinitely variable from 1 lumen (low) up to 55 lumens (high) and it runs for 58 hours in low mode. About the size of a flash drive, the slim profile makes it great for hanging around your neck, slipping in your pocket, adding to your survival kit, or even putting on your keychain.

A single switch operates all functions for convenient one-handed control. The interface is simple. For low light, press once for 1 lumen, the press again to turn off. For max brightness, press twice for 45 lumens, then press again to turn off. For a quick, momentary bright light, press and hold for 55 lumens, then release to turn off. For a brightness between low and high, press twice and hold then release at the desired brightness. Press again to turn off.

To prevent the light from turning on in your pocket or pack, with the light on, hold down the button for 3 sec. TUBE will lockout, signaled by a quick LED flash. To unlock, hold down the button again for 3 sec.

TUBE has a built-in, high-efficiency Li-ion rechargeable battery with an intelligent protective charging circuit and a Micro USB connection. Since you probably already carry a spare battery to charge your phone, there’s no need to worry about running out of juice or replacing batteries, just plug into a power bank, wall charger, computer, or car (USB cable not provided). An indicator light lets you know when the charge is complete. A rubber cover protects the USB port from dirt and moisture.

    Rubber band them to glasses for a headlamp!

    Wrapped a couple rubber bands around mine, stuck it on my glasses stem when I needed my hands free. Brighter than expected for a single LED.

    Perfect neck light

    Posted by Chris Hennessey on 26th Mar 2022

    I like to have a small light on a piece of thin shock cord around my neck whenever I'm in the woods. This little guy is perfect because it lays flat against me and doesn't roll around and get twisted like the mini aluminum barrel flashlights do. Plus it's bright, easy to use and rechargeable. I ordered three.

    Rechargeable and light weight

    Posted by Andrew on 31st May 2021

    This little flashlight was the smallest I have seen that can be recharged through a USB port, which saves on batteries and makes use of power bank/charger weight I already carry. I taped a piece of Velcro on it to attach to the bill of my hat so it can be used as a headlamp. On the high mode, it gives plenty of light for a short night hike/setting up camp in the dark.

    Best Light for its Size!

    Posted by Deb on 25th Feb 2021

    I love the choices for the brightness of the light. I was impressed how much light this gives out on the highest mode. A charge lasts a long time and it recharges quickly. It is easy to operate even with gloves on!

    Light, bright (enough)

    Posted by Unknown on 30th Aug 2020

    I end up doing a fair amount of hiking after dark and like to bring two lights - one bigger and brighter with a longer burn time for hiking, and then a second smaller option as a camp light and backup. I got this to downsize my smaller light option and it does the job. Super light, bright enough for camp needs and lasts a long time at low settings around camp, and bright enough to be a short term back up option. I was using a Thrunite thrunite ti3 v2, which does a good job, but this is even lighter, fulfills the same purpose for me, and is USB rechargeable.

    Amazingly bright.

    This thing is like a headlight on a car. I'm using one for camping as a backup light.
