It's dead simple to operate, it's relatively comfortable, and it's less than 1.5 ounces. I thought the more-expensive NU25 was going to be my go-to for backpacking, but I wound up getting lost in the light settings every time I wanted to turn the thing on. I am a fully-grown adult person with a college degree and the NU25 would confound me every single time. Not so with the NU20! Instead of having one power button and one "mode" button with different click types to memorize, the NU20 has basically one button for the white LED, and one for the red. Buy this and remember "Right is red, left is LED" and you're set.I think the main feature you're giving up with this headlamp is access to a flood light AND a throw light, which can be useful. The white LED on this one is a little more throw-y but perfectly suitable as a task light--and actually really impressive as a searchlight. It just won't be as comfortable and diffused as flood lights on models like the Black Diamond Spot.

Nice and light weight. Operates exactly as advertised. Have used it several times now hiking and around the house.

The Nitecore NU20 Classic Ultralight Headlamp stays true to its lightweight design, now featuring a USB-C port for charging and a slightly larger battery. It weighs .9 oz without the head strap—about the same as the original NU25 (non-UL version). However, I’m puzzled by Nitecore’s numbering scheme. Why call this the NU20 when there was already a NU20, just like they did with the NU25UL when there was already a NU25? This new NU20 is actually more similar to the original NU25, so why not just increment the numbers to make it easier for customers to understand the product progression?That said, the light itself is great. There are four brightness levels for the main spotlight, two levels for the red light, and a CRI flood light that works well in a tent or around camp, just like the original NU25. However, I’m not a fan of the plastic casing—it looks and feels cheaper than previous models due to some unnecessary textures they added. The headband is lighter than the original straps, but it still feels bulky for such a small headlamp. Thankfully, the headband is removable. I made my own mod by using a simple elastic band cut to size with knots on each end, snapped into the upper slots of the headlamp. This brings my setup to a total weight of 1.1 oz, making it truly ultralight.On the downside, the lockout feature now takes much longer to activate and deactivate, which feels unnecessary. The buttons, while seemingly more water-resistant, are also harder to press—not impossible, but enough to make it slightly frustrating.As a comparison, I’ve also been using the new NU25UL. After several night hikes, I’m not a fan and actually reverted back to using the original NU25 (non-UL version). While the NU25UL cuts down on weight, it doesn’t deliver the same level of comfort or functionality I’ve come to appreciate in the original.

I ran this for over an hour on turbo and the battery still showed half. The lamp did get hot and smell plasticy after that so I turned it off. Very bright, the red light is a nice touch but could be a tad brighter but I guess that's the whole point not to blind/annoy others as you work/hike in public spaces. The band originally looked uncomfortable to me but it is not at all and the lamp is so light I forgot I was wearing it until I went moved and noticed the beam emanating from my cranium.

Works well for me, the buttons are well placed and intutive to use, light weight and comfortable (fell asleep with it on one night and woke the next morning unable to find it, so comfortable I for got It was on my head still)

Removing 1 star because brightness is not adjustable other than the preset brightness levels, and it doesn't feel very durable, but otherwise, this is the perfect headlamp. I like how incredibly fast it charges, and how lightweight it is. I like how it does not do the anoying "step down" brightness constantly when the battery gets low the way my nitecore HA11 does. It still has the step-down feature, it's just not sensitive, and it only did the step down thing once in 5 months of using it. The best part about Nitecore brand headlamps is the headband. These headbands are in a league of their own, and are 100x better than standard headlamp headbands. I like how quickly I can adjust the headband tightness such as if I put a backwards ballcap on or off. I wish this headlamp came with the hatclip like the HA11 does though. The headband is mildly glow-in-the-dark. This is the most lightweight headlamp I have ever used, and it is very comfortable, I can even lay down in bed with it to read on the dim setting. But sometimes the middle brightness setting is too bright for me and I wish I could hold the button to change the brightness, analog style. The 2 brightness levels on the red light are nice but the dimmest setting is too dim, almost unusable. I only used it once when stargazing. I like that there are 4 brightness settings of main light, and I like the auxiliary floodlight setting. But overall, I think the price is too high. I camp and RV full time and I need 4 headlamps, but at $25 each I can only justify having 1 of these. If they were less expensive, I would buy another one and also 2 of the white ones for running/cycling too.
