The Nitecore T Series Rechargeable USB LED Flashlight is a perfect EDC tool when space is at a premium. With 45 lumens that runs for 1 hour, or 1 lumen reading light that runs for 48 hours, plus the flexibility of a rechargeable lighting system that fits in your pocket, it's a convenient little light for everyday use.
Besides for offering you low and high output modes, the Nitecore Tube offers momentary illumination, so the light only stays on at full brightness while you're pressing the button. You can even vary the brightness by holding the button down in variable brightness mode so you can run at half strength or whatever the situation calls for.
The lanyard loop on the back is made of stainless steel, and will withstand a 77lbs force so the light won't break off your carabiner if you snag it!
Approximate recharge time is 2 hours.
