Nitecore SENS Mini LED Flashlight

A lumen is the SI unit of luminous flux, equal to the amount of light emitted per second in a unit solid angle of one steradian from a uniform source of one candela. Multiply that by 170 ad you’ve got the blindingly bright Nitecore SENS Mini. But the Nitecore is more than just an LED light, it’s rugged, waterproof convenience that fits in the palm of your hand with room to spare. A single CR2 battery powers this flashlight to more than 69 meters at full power and a built in active dimming sensor knows the angle at which the Nitecore is held and adjusts the light level accordingly. Of course, you can set the light to a fixed setting of 170, 50 or 20 lumens if you prefer manual operation.
