What sets the Nitecore NU43 apart from other headlamps? How does it compare to the NU25 or NU33 headlamp?

Featuring a high-capacity rechargeable battery, the NU43 achieves an impressive 1400 lumens. It's a more robust choice for professional works, household tasks, and camping activities where both high brightness and prolonged battery life are crucial.

How to operate the headlamp?

The NU43 has two distinctive switch buttons for easy operation.

What is the red light or the Ultra-low light for? Can I turn them on without going through all the other settings?

Both light sources are commonly used for preserving night vision. When the light is off, long press the Mode Button for 1 second to turn on the auxiliary red light directly, or double tap the Power Button to turn on the Ultra-low light directly.

The headlamp flashes but does not turn on when I tap the button. Is it the LOCKOUT mode? What do we use it for?

LOCKOUT is a feature designed to prevent the unit from accidental activation while it's stored in your bag or pocket. To enable or disable the LOCKOUT, press and hold both the 'Power' and 'Mode' buttons at the same time for a duration of 2 seconds.

Why does the light sometimes automatically dim down? Can this proximity sensor be disabled if needed?

The NU43 headlamp is equipped with a proximity sensor to avoid overheating. If the sensor identifies an object in close proximity, it automatically reduces the brightness. You can disable it temporarily by tapping either button after it's activated.
