The world’s lightest 18650 battery operated rechargeable headlamp, with maximum output 1400 Lumens, built-in 18650 Li-ion battery with a capacity of 3400mAh and weight 116g.

Nitecore NU43 Flashlight Headlamp is the world’s lightest 18650 battery operated rechargeable headlamp, with maximum output 1400 Lumens, built-in 18650 Li-ion battery with a capacity of 3400mAh and weight 116g.

With the innovative design of the built-in Li-ion 18650 battery, the NU43 can produce a maximum brightness of 1400 Lumens while being a perfect combination of the large capacity of 3400mAh and the very low weight of 116g, breaking the performance and capacity limitations of common lenses powered by 18650 batteries.

The Eco-friendly wide (32 mm) head strap is designed with holes to be light and comfortable, it has fluorescent strips to warn pedestrians and vehicles at night and has a hidden wide silicone strip that guides sweat away from the eyes to the sides of the face and also helps to keep the strap from slipping on the head.

The Nitecore NU43 Headlamp has multiple safety guards:

• When the built-in optical sensor detects an obstacle in front of the lens, the light intensity will automatically dim so that the lens does not overheat.
• By rotating the flashlight on its base, you position it so that the buttons are protected from accidental activation during travel or transportation.
• Lock function for both buttons to prevent accidental actuation effectively.

The NU43 head lamp is operated by two switches.

• A Power Button for On / Off and Brightness Adjustment,
• And a Functions Button for Light Source Selection

The head lamp features a red lighting, ideal for map reading, emergency response, wildlife observation, stargazing, night photography and many other uses.

In addition a very low white 8 Lumens light, is accessible with a double press of the power button. Ideal lighting for the dark when strong lighting is unnecessary.

The center of gravity of the lens rotates around its axis. This design allows for a small torque and short shift when adjusting the lens, which significantly reduces the pressure on the forehead from the lower end of the arm, to achieve a more stable and comfortable experience without shaking during intense exercise.

In addition, it can be quickly adjusted with one hand to select the desired lighting angle.

The stand can be rotated 72 degrees and can be moved up quickly to avoid direct illumination of personnel at emergency situations.

The light beam has a wide-angle of lighting that reaches 100 degrees.
