The Nitecore NU43 is a small and light headlamp capable of delivering 1400 lumens to the Turbo and reaching a distance of about 130 meters with a maximum light intensity of 3800 cd. The NU43 is powered by an internal non-removable 3400 mAh lithium-ion cell which guarantees a maximum runtime on the lowest level of 165 hours ( 6.87 days) on a single charge. The Nitecore NU43 is equipped with two different LED emitters: the white main LED for which it is possible to select five levels of brightness: Turbo (1400 lm) High (600 lm), Mid (300 lm), Low (100lm), Ultralow (8lm). In addition, special Strobe and SOS levels of 1400 lumens are also available. The lenses are of the TIR type with light transmission over 94% and guarantee a clean and balanced beam. To the left of the main LED there is a red auxiliary LED for which it is possible to select the constant on or slow flashing mode.The Nitecore NU43 has two different switches for interface management. A power button for switching the light on and off, and for varying the different brightness levels and a Mode Button to switch from one mode to another. A double press on any switch will turn off the light when the flashlight is on. On the Nitecore NU43 there is also a battery status indicator: this is composed of a series of 4 blue LEDs that light up to indicate the residual capacity of the cell: for example, 4 LEDs on means 100% capacity, only 1 LED on capacity about 25%. The user interface of the Nitecore NU43 also provides for the electronic lockout of the flashlight to avoid accidental switching on: this can be done with the simultaneous click of both switches. In lockout mode, any brightness level or special levels are not available: this is ideal when the flashlight is stored inside backpacks or pockets. The flashlight is recharged through the type-C charging interface hidden in the side part of the flashlight. A full charge takes approximately 2 hours. The water resistance is IP68 while the drop resistance is 2 meters. The body of the NU43 is made entirely of PC and aluminum: this makes the flashlight very light and practical to carry. In fact, the weight, including the battery, is only 116 grams. The elastic leaves are comfortable, soft and particularly elastic. Not tired if used for many consecutive hours. Super comfortable when jogging holds the flashlight securely in place on your head.It is also possible to rotate the light from top to bottom to direct the beam exactly where it is needed. The Nitecore NU43 is also equipped with a proximity sensor which automatically decreases the output when an obstacle is found in front of the lens. The brightness will return to the set level as soon as the obstacle is removed. This increases the safety of the flashlight.
