NitecoreNU45 1700 Lumen Headlamp, USB-C Rechargeable Fast Charging, Long Runtime for Camping, Running, or Work, with Auxilary White Reading Light and Red Light

Love the brightness and the lumens are good.

Best for night time construction. This light has everything you need. Love how it has the red light for when I work next to traffic and the ease of switching between the different functions couldn’t be easier.

I've used this on a few trail runs. No longer than a three to four hours in the dark and it's worked perfectly. I really like how it clips onto the headband along with how easy it is to adjust the beam up and down.I added a strap on the shoulder of my running vest and attached the headlamp to it. I've enjoyed running this way and not wearing a headband. I can scroll the headlamp up or down to change how far in front of me the beam goes. The scrolling ability is built into the housing of the lamp itself.The LEDs are very bright and have multiple settings. I tend to use a lower setting at dusk and brighter as it gets darker. I tend to use the middle setting the most. The red light is also great when your standing with a group or at an aid station and don't want to blind everyone but still need to see.

First and foremost, this is a very bright head-mounted light. I purchased it as an upgrade over a prior Petzl model. The UI with the buttons took some getting used to, but after reading the manual I now have them memorized. I really like the lockout feature since this lives in our RV. It's nice not having to worry about it accidentally turning on in transit and possibly causing a fire. The flood and spot pattern options work well. It's also super nice having the red LED with two power levels for my nighttime photography, fishing, etc. I was able to purchase it for $20 off retail due to promo, but I still think it's a worthwhile purchase at full price once you learn the functionality of the buttons.

We had the older Nitecore NU25 headlamps and used them extensively - from camping trips to walks around the neighborhood. We loved those headlamps, but I wanted to change all of our rechargeable gear to USB-C to help simplify our lives and so I ordered the NU45 for both the USB-C interface the greater lumens. It is a durable beast of a headlamp - this thing will take quite a beating. I've used it on 2 camping trips so far and it really lights up the campsite and trail when I need it to. I had to get used to the different sequence to turn off/on and cycle through light settings. It does have more light settings too with 2 different white lights with multiple lumen levels. I especially enjoyed the 2 lumen levels for red light which is what I use the most while camping. The only drawback is that this headlamp is big, much bigger than our old NU25's. It comes with it's own drawstring bag which is nice, and thankfully not black in color but white so it's easy to find, but it only makes it bigger when storing and packing (like in a fanny pack). For this reason I'm knocking it 1 star. But if size is not an issue for you then you won't be disappointed in this headlamp.

One of the brightest head lamps i have ever used. I use this one for hunting and man this one shines bright. Love that it will recharge on my power bank

Pros: great brightness, multiple modes, wide beam, VERY light thanks to the polycarbonate (aka plastic) housing, and I really appreciate Nitecore's graph plotting the lumens vs runtime behavior in the manual.Cons: battery is sealed!! Did not expect that considering their higher end models have removable 18650s. NO memory. Aggressive step brightness step down such that quoted lumens turbo and high needs to be taken with serious exceptions, although this is more expected due to the plastic housing. Wonky UI, which appears to be standard across their lineup, but I still don't like it. Infamous green tint at lower brightness levels from the main LEDs. I've concluded this is an inherent trait of Nitecore's UHi LEDs which doesn't bode well considering they're progressively moving their entire lineup to UHi LEDs

I use Nitecore a lot while I’m caving or hiking and it rarely ever disappoints me. It’s usually every bit as good as the more expensive brands. It’s bright, and holds up pretty well underground even when it sometimes gets bumped around. It’s not overly heavy or bulky either.
