Rechargeable Headlamp 4000 High Lumens, Super Bright LED Head Lamp with Motion Sensor, 12 Modes, IPX7 Waterproof, 125° Adjustable, Zoomable Headlight for Adults, Camping, Cycling, Running

Bright, Tough, and Hands-Free — My New Go-To!
I bought this headlamp for night work around the house and camping in Puerto Rico, and wow — it’s a beast! Super bright (like light-up-the-whole-yard bright), and the motion sensor feature is actually useful when my hands are dirty or full. The 12 lighting modes are great — I usually stick with the high or zoomed-in beam, but the warning lights and strobe came in handy during a power outage.The USB-C fast charging is a win — no more weird cables. The battery lasts long, and the display helps keep track of the charge. It’s surprisingly comfortable on the head and stays put, even when I’m sweating. Plus, the thing handled rain like a champ — the waterproofing is no joke.If you’re doing anything outdoors or hands-on at night, this headlamp is totally worth it. Feels like one of those smart buys I’ll be recommending to everyone. 🔦💪🏽

Great quality & very bright light
This headlamp is awesome! Much better quality then some of its competitors. Other brands and models say they are brighter, nope! The battery compartment is made of quality materials and is enclosed nicely, not made with a flimsy battery compartment latch made of cheap plastic. This is a great buy for the price.

Great light -mostly!
Update 27Nov24:More cons: The sensor is too sensitive, and it only works in bight mode, not in dim or flashing.Exceptionally bright, this is a pretty nice headlamp. Zoomed all the way out, and standing 8 feet from a wall, it creates a spotlight about 10′ in diameter. At the same range, zoomed all the way in, it creates a pinpoint spot about 5-6″ in diameter. And it’s bright enough that when I zoom in and shine it about 300 feet away, it makes a circle I’d estimate 12-15′ in diameter. So you can get quit a significant amount of light on a smaller target far away.Pros:1. Brightness; it’s about the brightest one I could find, and if my Lux meter app on my phone is accurate (I tried 2 of them with same results), when I shine it point-blank, it reads a max of about 920,000 lux.2. The biggest plus for me is when zoomed in. The other headlamps I have had just made s square (shape of the emitter). I also tried a headlamp from Amazon with the title “Rechargeable Headlamp 2Pack, 990,000LM Bright Head Lamp…”, from the “LNRYY” store (gotta love those Chinese company names), which registered the same lux on my meter, and it not only made a square zoomed in, but was very notably much dimmer at that same 300-ish foot distance -pretty useless at long range. It was about the same price for 2 instead of 1, but I sent them back and ordered another of these.I wanted a bright light for far-away uses, and this one gives you a beautiful flood of light for a large area zoomed out, and great is zoomed in, or anything in between.3. Has a battery strength indicator.4. It seems pretty well built, with a couple exceptions (see cons).ProCons (double-edged sword):1. Though some might consider it “feature-lack”, I like that it only has high, low, and strobe. Strobe seems pretty pointless for me too. Probably SOS would be better, since I would only ever use strobe under similar conditions. Some other headlamps I’ve got have 6 options -options I’ll never use- and you have to scroll through them all to turn the light off.2. There is a button on the back of the battery pack, near the battery level LEDs. When the light is on, these white level LEDS are on as well, so you can see your battery condition. When the light is off, you need to press this button, which has a different purpose, but is the only way to see the battery level while the light is off. The button turns on some little dancing red and blue LED ‘lines’ that ‘circle’ / blink. The purpose is so that if you were walking or bike riding, someone approaching (driving) from behind you would see these little LEDs and hopefully approach more cautiously. And though I doubt I will ever use it, I think it’s a nice feature. What is less nice is that, again, it has all these unnecessary options. They thought it would be some kind of selling point to have 6 different patterns (rotating red & blue -fast and slow; blinking purple -fast and slow; blinking red, then blinking blue -fast and slow), but it only means that if you turn it on, you have to click 6 more times to get it off. So if I want to know my battery condition, I will always just turn on the headlamp. At least that way I only have to click a button 3 times instead of 7.Cons:1. The switch. It has High, Med, and Strobe. Unfortunately, you have to cycle through all to turn it off. I have other headlamps where they figured out that if it’s been on in a given mode for a few seconds, then clicking again just turns it off. Or holding the button turns it off -but they couldn’t do that with this one, cause holding it turns on the motion sensor on/off toggle option. And the motion sensor seems a bit too sensitive, so that’s a small con for me as well.2. The rechargeable battery is not (easily) replaceable. But you CAN if you try hard enough. You have to unscrew the compartment, unplug it, get 3 new cells and wire them together, shrink wrap, and solder the little plug onto your new battery assembly. That is what I will do it if lasts that long. The other one I returned had a compartment to just change the 3 batteries; no heat-shrink battery module. It takes those long lithium ion batteries -18650’s I think.3. It gets hot. Probably no way around this considering the brightness, but if you need to leave it on for an extended period of time, you best be careful not to burn yourself. People have largely different tolerances to heat pain, and mine is not especially high, but…I tested it, grasping the black adjustment ring:After 30 minutes, it was starting to be excessively uncomfortable after grasping it for about 5 seconds. But after 60 minutes, grabbing it for more than a second or two might actually yield a 1st degree burn. Not really a huge deal, or reason not to buy, but buyer beware :-)4. To adjust to light vertically, you just tilt the light up or down: there is just a little cylinder with sharpened bumps on the light housing; kind of like a gear, but with little triangular teeth that come to a point. Then on the head plate, there is another (also plastic) little triangular extrusion that presses against the gear. Two things strike me about this. Number 1, there is a lot of play -perhaps 15 degrees- between each ‘setting’. Not at all precise. And more importantly, it very much has the feel of something that is just going to wear down if used very much. I’m already trying to think of what I could do to improve it, but nothing simple comes to mind. This is quite unfortunate, because I feel pretty certain it will fail if I use that adjustment much.So, quite a few cons, but I’m still keeping it. 🙂

Let There B Light
Place this on your head. It is so bright you’ll have to wear sunglasses just to see what your working on. Rechargeable so no batteries.
