The Nitecore NU33 headlamp has an impressive maximum output of 700 lumens and a range of up to 135 meters. The light is powered by a built-in rechargeable 2000mAh Li-ion Battery.

The headtorch is ultralight and compact, weighing just 95.5g.  It has a durable and rugged construction, including the front housing which is made from aluminium, providing high efficiency heat dissipation and ideal for outdoor environments. The NU33 headtorch is perfect for night running, outdoor adventures and camping, plus lots more!

The NU33 features a primary white light, plus an auxiliary red light and an auxilary white light. The auxilary red is useful when stargazing, wildlife observations, night photography and emergency response. All outputs can be accessed with the user-friendly dual button interface. A battery power indicator can also be accessed with a short press of the mode button.

Advanced Temperature Regulation (ATR) adjusts the output of the NU33 based on the working and ambient temperatures. This feature ensures that the device maintains optimal performance while preventing the LED from overheating. The output measurements account for the total runtime, including periods of reduced brightness due to temperature changes or built-in protection mechanisms, which may cause the brightness level to drop.
