sofirn Headlamp, 1200 Lumen Rechargeable Head Lamp with Bright SST40 LED, Waterproof, for Kids and Adults, for Camping, Running, Hiking, Emergency, Outdoor, Hard Hat

Nice versatile car camping, construction site, emergency headlamp. Heavier than my backpacking camping headlights but far more light output. Angle adjustment is nice, the light modes are easy to figure out. The USB charging option is useful. I have a bunch of 18650 rechargeable batteries that get used in a variety of flashlights and headlamps and usually charge a bunch of them on a separate charger and keep them fresh. Does eat batteries pretty quickly in high mode and the battery gets warm after extended use in this mode.

My dad and I each have one of these D25S headlamps - which we bought to replace some cheapo-LED lights that needed to be retired. Just to give you an idea: the old lights required a AAA battery cell, were heavy (1/2 lb) and only 100 lumens. The 3 AAA batteries required would last 1 hour, on a good day. We even bought Eneloop rechargeables to save on the cost of batteries - but it just wasn't practical because the light just didn't last long enough and recharging took too long - and that says a lot about how poor-a-design the old lights were, because the Eneloop batteries typically last longer [in our experience] than traditional batteries.Anyway, onto the D25S headlamp. Long story short - my dad and I really dig this lamp. We use them for different purposes, but in any case, it's something you'll want to have in your arsenal of useful tools.The D25S is great for a number of reasons. Here's my take on it (not necessarily in order of priority):1. It's rechargeable via USB with an indicator light to dictate charging/charged (red/green, respectively)2. The 18650 battery is stored in the same compartment as the light (not on the back of your head in some brick, like many LED's on the market)3. The strap is very soft, pliable, and minimalistic - will fit anyone comfortably, even if you needed to wear a hat.4. Most importantly, it's bright! VERY BRIGHT. The only thing brighter that I own is my Hikari LED headlights on my car (highly recommend if you're tired of halogens or HIDs).5. The push button for turning the light on is simple - you don't have to fiddle with it to work as you do on many flashlights or headlamps. It's also coarsely textured so if your hands are wet or gloved, you can press the button easily.6. The fixture swivels so your neck doesn't have to.7. This strap does not interfere with the hair on the top of your head, which can make for a real "head-scratcher".There are a few things I wish were better:A. I wish there were clasps from the fixture around the light instead of just the two snap rings. If you were to bump it or drop it hard enough, the light might jump out of the head fixture. Adding clasps might add a little weight, but it's a good insurance policy if you're wild with your light [presumably from excitement of the brightness :].B. A lock for the strap - sometimes, the strap will loosen on its own. If there was a lock or a clasp to keep the straps from moving, it would take less time to adjust and readjust when taking on and off the light between uses.C. A little extra padding on the light mount at the forehead - the light can heat up a bit on turbo mode and when it does, you can feel the heat around your forehead. Not a problem in the cold, but in the heat - can be a little uncomfortable. A rubber insulated pad would most likely reduce this, but at the cost of added weight. The rubber might not be needed if...D. There were a few more cooling vanes on the light housing- not that it overheats, but in turbo, the light gets very warm (as a powerful LED does anyway). For very obvious reasons, heat is no good for a rechargeable battery or the LED and the more power cycles in less-than-optimal temperature ranges, the less likely the battery and LED will last a long time.For the price - you can't beat this light. Sure, there are a few things I wish were different, but I really am quite pleased with it. It's SO MUCH BETTER than the other lights on the market in 2019, and it's certainly better than anything you could buy locally in a hardware store or hunting/fishing outlet. It's also much less expensive.I really quite enjoy this light [as does my dad]. It's saved us both lots of time and labor with fiddling with some big, hefty 'industrial' light to illuminate a job - big or small, from 2m soldering to big rig oil changes. It's hard to believe we've worked this long without such a bright addition to our toolbox(es).

It's cool. And so small package, right as it should be. The construction of the flashlight is simple, as an axe. But well-made quality, i like it too. I've recieved it with uncharged battery (3.7v), what i accepting as normal. Then, I've charged it on Lii-500 with 1A current, and the battery consumed 3000 mAh, as it should. I believe its totally okay. Charging type-C cable is so short (1ft), it might be 2-3 feet.Today I've used it for some home electricity repairs jobs, and it helped me a lot! I like, that the flashlight has no direct concetrated lightspot, but it's smooth. Mean, it'll not blind an owner, if a lightflow will reflect from something, like it happens with some hand flashlights.On the maximum brightness it does not warming up so much, as someone said before. Excuse me, I'm at Dominican Republic, in the middle of the summer, with daily in-shadow temperature around 40C⁰. I've met enought with hot conditions, believe :)Button is okay, i guess it will work for a long. A circle around the power button shows how the battery charged for a few seconds on the powering on, approximately 5 seconds i guess. I love, that the flashlight got the memory function, and it start with the brightness I've left before. The flashlight has very light weight, it's comfortely to use it on the head.Gonna recommend it to others. It worth those ≈28$
