Illumination & Gentle High quality
In terms of general illumination, the NU27 impressed us essentially the most. The headlamp has a lumen ranking of 600, however as we frequently level out, lumen rankings don’t at all times inform the complete story. For instance, the Petzl Actik CORE additionally has a 600-lumen ranking, however when examined aspect by aspect, the NU27 seems considerably brighter. Curiously, the “excessive” setting on the NU27 is rated at solely 400 lumens.
The extra 200 lumens are activated in turbo mode. This implies the NU27 is brighter than its ranking suggests. We have been additionally impressed with the throw of the NU27’s beam, which outperforms even a few of our favourite headlamps with comparable lumen rankings.
That mentioned, there’s room for enchancment. The beam is considerably spotty, and we’d wish to see a flood operate added in future fashions or at the very least improved floodlighting general. The headlamp additionally produces some odd lens-flare-like artifacts close to the sides of the beam, which might be disorienting at instances. Moreover, the colour rendering isn’t the most effective, that means the NU27 doesn’t do a wonderful job of precisely reproducing coloration throughout all three coloration temperature settings.
General, the NU27’s illumination exceeded our expectations, whereas the sunshine high quality is usually mid-tier however passable.
Burn Time
The burn time of the NU27 is a blended bag, although largely constructive general. In comparison with a few of our high performers, it’s on the decrease finish, however when in comparison with different ultralight headlamps, it’s on par and even barely higher than its opponents. Because of the ultralow operate, you possibly can rise up to 57 hours of sunshine per cost beneath best situations. Nevertheless, the ultralow operate solely gives 6 lumens, making it appropriate for round camp however inadequate for on-trail use.
From there, burn time decreases considerably: about 13 hours on low, 6.5 hours on medium, and simply 3 hours on excessive. Nitecore doesn’t present a burn time for the turbo setting, however in our expertise, the battery drains shortly, and you’ll count on not more than an hour on turbo. That mentioned, the excessive setting is shiny sufficient for many actions. Actual-world burn instances will range based mostly on the settings used and the way lengthy they’re engaged. General, whereas the upper settings carry out effectively, we’d wish to see higher burn time from the low and ultralow settings.
Weight
Weighing simply 1.98 ounces, the Nitecore NU27 nice for ounce counters. Whereas not absolutely the lightest in our testing pool, it ranks among the many high three ultralight choices. It’s excellent for ultralight backpackers, path runners, or anybody seeking to reduce pack weight. Any headlamp beneath two ounces is a strong alternative for these aiming to cut back gear weight.
The light-weight design is very noticeable throughout long-term use, because it minimizes fatigue. We discovered it straightforward to neglect the headlamp was even on our heads, whether or not throughout an evening hike on the Colorado Path or operating within the entrance vary. The diminished weight means much less pressure, making it simpler to benefit from the process at hand.
Whereas lighter headlamps can be found, the NU27 strikes an incredible steadiness between its low weight and general brightness.
Consolation
Ultralight headlamps might be difficult to judge for consolation. Whereas they’re not inherently uncomfortable, weight financial savings are sometimes prioritized over consolation, particularly when in comparison with heavier headlamps. Ultralight fashions usually use fewer supplies, leading to much less padding and strap materials, generally impacting consolation.
That mentioned, we discovered the NU27 to carry out very effectively when it comes to consolation. Naturally, weight performs a major function—much less weight in your brow results in a extra snug expertise throughout extended use. Regardless of missing heavier, softer supplies, the light-weight, balanced design helps reduce fatigue, making this a headlamp you possibly can put on all night time.
Nitecore does a very good job of minimizing plastic-to-skin contact, though some uncovered plastic stays on the again of the headlamp physique. We additionally discovered the strap extra snug than the shock-cord model straps usually discovered on ultralight headlamps. The strap options air holes to reinforce breathability.
Ease of Use
Just like different Nitecore headlamps, the NU27 is designed with dual-button performance. On the highest of the headlamp physique, there are two buttons. The bigger button is the ability button, which turns the headlamp on and off and adjusts the general brightness when it’s on. The smaller button is the mode button, which cycles by the headlamp’s three coloration temperatures and accesses the purple mild operate.
Headlamps with a number of options usually have a little bit of a studying curve, however we have been in a position to determine most capabilities throughout our first use while not having the directions. Nevertheless, we did seek the advice of the directions to learn to entry the particular modes (SOS, Beacon, Gradual Flashing). Not like some directions with poorly thought-out illustrations, Nitecore gives clear,easy-to-understand instructions.
The charging port is straightforward to entry, and attaching the cable is easy. The strap is straightforward to take away, and the included pocket clip attaches simply as effectively, although eradicating the clip can really feel a bit difficult with out the priority of breaking it.
Our major criticism is that the buttons’ small dimension and low profile make them troublesome to press with medium to heavy gloves on which was a difficulty for us throughout chilly night time hikes within the mountains.
Options
The options of the Nitecore NU27 are one other standout side. As we’ve talked about, the NU27 means that you can change between three totally different coloration temperatures. Whereas coloration temperature is a matter of non-public desire, these choices additionally enhance visibility in numerous environmental situations.
The nice and cozy mild (3000K) is less complicated on the eyes and works effectively in foggy or wet situations. Impartial white (4500K), the commonest coloration temperature discovered on headlamps, affords a extra pure mild for on a regular basis actions. Lastly, cool white (6500K), although a bit harsh, enhances visibility in out of doors environments. It’s also possible to choose from 5 totally different brightness settings throughout all three coloration temperatures. Moreover, the purple mild operate affords two brightness settings.
Past that, the NU27 consists of SOS and Beacon modes, USB-C charging, a battery life indicator, and a locking function. The field additionally comprises a diffusing stuff sack, which lets you use the headlamp as a lantern, in addition to a clip that may exchange the strap.
Whereas the options of the NU27 are a serious plus, the number of brightness ranges and lighting modes would profit from the addition of a reminiscence operate. This is able to prevent from having to reset the colour temperature and brightness every time you flip the headlamp on and off once more.
