Update: I've been using the headlamp often for months now. In the original review I said that battery life is excellent. That's true only at the lowest two settings. If you need more light, you'll get about 2.5h from 3000mah cell. So, if you were using this lamp for work and need to pull a full shift, you'll need three fresh batteries. At the lowest red or white setting, it'll run for more than a day on one battery. Six-eight hours for the next highest setting. The upper two settings eat up the battery, but then, they also make a lot of light. 40 years ago, the headlamp of an automobile didn't make this much light. the housing gets warm but not hot.A potential wear item: the light "clicks" and stays in place by aluminum teeth on the lamp body against plastic teeth on the headband. The plastic is going to wear out long before the aluminum. Manufacturer should provide a spare.++++++++++++++++++++++++++++++I rarely leave a 5-star review. Five stars is for an exceptional product. If it's merely as advertised, it's four stars. This headlamp is so much better than its competitors that it deserves five-star recognition. I've purchased and returned several red headlamps. They're all big and bulky, or they require you to switch through white or strobe to turn them on/off. They have battery compartments that obviously predate lithium batteries, and most of it is empty space. One crappy piece of junk after another.This headlamp was designed by someone who has a clue -- a person who apparently uses their own gear. It's usefully dim, and usefully bright. There's no useless strobe or SOS, and you don't have to turn on a white light to get to the red light. Battery life is excellent. On the dimmest red setting, this light is good for astronomy -- that's rare. The two brightest red settings are bright enough to hike a steep trail in the blackness under a tree canopy. The reflectors are just right -- not too focused, not too diffuse. The built-in USB-C charger works well. The button is easy to work while wearing gloves. This is an awesome headlamp for my purposes. This one is a keeper.That being said, it has one definite flaw: there's no protection against the light turning on in your pack if the button gets pushed into other gear. It needs a raised lip about 6mm around the button, just like the raised lip that forms when you unscrew the cap to charge the light. The battery cap can be unscrewed a bit to disconnect, but I'm not sure how reliable that is. This is the only flaw I've found with this light.Also, and this isn't a flaw, just a tradeoff: it's heavy (120g with battery), compared to my regular Black Diamond light (82g with batteries).

I’ve owned over 20 different headlamps, I camp/hike/hunt a lot. Most headlamps out there cast what I would call frustrating beams; they’re either too wide-angle and you can’t see ten yards ahead, or they’re too much a spotlight and you have no peripheral. For illustration purposes I’m going to compare this headlamp to a Zebralight Floody.Now, nothing I’ve seen beats the Zebralight. That thing casts a wonderfully pure 90-degree beam that still gives you about 30yds of distance (and that isn’t even its max setting). It can be cranked up to an uncanny level. That said, this one is similar. It’s in the same ballpark. The white beam will do anything for you that the Zebralight will do on foot. For something like riding a bike in the woods at night, you’re moving faster which means you’ll need the brighter ability of the Zebralight. But at such a price difference, to get this level of performance is astounding.The beam is actually a spot/flood, meaning it’s stronger in the middle and there’s a definitive difference in the peripheral lighting. This isn’t as stark with the white light as it is with the red light. Overall though it gives a great balance of near/far viewing for hiking. Hope this helps people out there get a sense for what kind of light you’ll get.So other than the actual beam of light, what sets this apart from the rest of the field? Simplicity. It’s a simple red or white light. Click to turn on the white, hold to cycle through four brightness levels. For the red you hold to turn on, then just as with the white you hold to cycle through four brightness levels. It also remembers your last setting even with the battery removed. Super. Stinking. Simple. No flashing strobe modes or 16 brightness levels or multiple colors or any of that. It’s amazing performance in a very easy-to-use platform that gives you both red and white light, and both are actually usable. Perfect simplicity.FYI if you’re wondering why red light, it isn’t just because it doesn’t disturb wildlife like white/blue light does, it’s not just a hunting thing. It also saves your night vision. If you’re using the white light and you turn it off, everything is pitch black for a while until your eyes adjust. With the red light, once you turn it off it’s like your eyes are already adjusted and you don’t spend a few minutes blind. Red light is much better in the dark for that reason alone. Use the white for when you really need to see better.

This is easily the best headlamp I've ever owned. It's super bright in both white and red modes and dimmable.I LOVE that it returns to the previously used brightness without having to click through them all.I LOVE that I can power on directly to the red light without having the white come on so that I can use it at night without causing my eyes to readjust.I LOVE that the recharging port is hidden and protected beneath a threaded cover for improved water and dust resistance.I LOVE that it is angle-adjustable and removable for in-hand use.And the batteries are not soldered in so I was able to buy a set of higher capacity rechargeable batteries with a charger that not only fit this but also fit some of my other flashlights and work better than the AAA batteries they typically use. So I have backups for this and better batteries for my other compact flashlights.The one I bought is "6pcs 1￵8￵6￵50 Rechargeable Battery 3300mAh W￵i￵th 18650 Battery Charger for Rechargeable 3.7V Lithium Ion Battery 26650 14500 Universal Charger for 10440 (Flat Top)",Amazon Standard Identification Number (ASIN) B0D93LWPQCI've no criticisms. I'm sure I'll be buying more of these to have multiples.I threw out other headlamps after using this. I'd rather buy more of these than replace the batteries in my other headlamps.
