Of course this is a headlamp, and so the primary means of carrying this light will be the headstrap.

Featuring a primary output from the Luminus SST-40-W LED and a maximum output of 1750 lumens and a range of up to 165 meters. This is not the end of the battery life, because it continued at this output, till after 4hours-14minutes it dropped to 1 lumen. The nitecore head torch features three light sources including the primary white light, an auxiliary red light and a high CRI auxiliary white light. The high CRI light is ideal for short range illumination, such as reading, as it reduces eye strain and accurately conveys colours. The light slips in and out of the plastic piece easily, with just two silicone loops on each end of the light.It still didn’t turn off, and continued for several hours, although I stopped the test before it turned off. The red provides excellent night vision and is ideal for outdoor night activities, such as photography and nature observation. At this point there is a sudden drop up to almost 3 minutes where, after a slight increase in brightness, there is a stabilized value up to almost 1h17m.

The oddity is the ring to take of to charge the light has to come all the way off and in an outdoor environment that would spell danger of loosing the ring. A high CRI auxiliary white light renders colors more like sunlight and can be used for an upclose flood of light when reading or working while an auxiliary red light helps users preserve night vision in dark environments.I am still very new at doing these types of measurements so I am no authority on on this subject, but please let me know if things don’t look right or you see anything that I could do to improve for next time.

A built-in battery voltage indicator under the button will display battery voltage each time the battery is installed and the end cap is tightened. Nitecore has also experimented with 2-stage long presses, where you hold to get, for example, ultra low, but if you keep holding it will jump up to turbo.

Reveal the port by unscrewing the USB cover on the right side of the torch and then simply plug the included cable into the charging port and the other end into a suitable USB power source. There is also a white auxiliary LED that has a high colour rendering index (CRI ≥ 90), a colour temperature of 4500 K and provides an output of 35 lumens. The NITECORE HC65 UHE Ultra High Triple Output Metal Headlamp features an 8-core ultra high efficiency UHE LED that shines up to 2,000 lumens.Nitecore HC65 V2 has a memory function and has only one button to manage: 5 primary levels with white light, 2 special levels (Beacon and SOS), 3 auxiliary red light levels and an auxiliary white light (High CRI ≥ 90). At around 20 minutes it settled at roughly 620-630 lumens and ran till it dropped again at the 2 hours and 5 minutes mark, to roughly 40 lumens. Nitecore HC65 V2 includes: Nitecore NL1835HP 3500mAh 18650 8A li-ion battery, spare o-ring, USB-C charging cable, headband and bracket.
