Headlamp Nitecore NU33, 700 lm

The Nitecore NU33 is a rechargeable headlamp in a compact size, which according to the manufacturer produces a luminous flux of 700 lumens and a range of 135 meters. Thanks to its light weight and robust headband, the NU33 is perfect for various types of activities, especially ideal for moving around in nature, and it is also great for e.g. for camping, trail running or, for example, walking the dog in the forest. The lamp has three LEDs, one for red light, one for low-power white light and the third for powerful and strong white light. An efficient LED in combination with an optical lens creates a very wide (100°) cone of light without sacrificing range. The light flux can be adjusted in 5 steps, and the lamp also has two separate flash functions (SOS and Beacon). In addition to white light, the lamp has a low-power red light, which helps maintain night vision. Red light works brilliantly, for example when reading a map, where the bright white light impairs night vision and temporarily blinds the eyes.

NU33 is equipped with a very high color rendering index (CRI>90), which reproduces the colors of the environment in as natural a way as possible. The NU33 is powered by a built-in 2000 mAh Li-ion battery, which can be conveniently charged via the USB-C port on the side of the lamp. With its four battery indicator lights on the side of the lamp, the battery's charge status can be monitored so that the battery never runs out unexpectedly. In addition, the headband of the NU33 is made of reflective fabric, so the user's visibility is further increased. Protection class IP66 enables use even in bad weather conditions, as the headlamp is completely protected from water and dust.

Ease of use is crowned by a very simple user interface. The headlamp is controlled via two switches, of which the larger switch functions as an on/off switch and a light flow adjustment button, while the smaller button can be used to toggle between white and red light. The NU33 can also be locked by holding down both switches at the same time for a few seconds, allowing it to be stored or transported safely without fear of the light coming on.
