Nitecore® TUBE is a tiny USB rechargeable LED light that puts out an impressive 45 lumens. The brightness is infinitely variable from 1 lumen (low) up to 45 lumens (high) and it runs for 48 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 45 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.

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