100000 LM Headlamp Induction Function, 7 Modes 50h Long Lasting Battery Life Head Lamp, IP67 Waterproof Zoom LED Headlamp, 90°Angle Adjustable for Outdoor Indoor Camping Running Hunting Car Repair

Very bright, easy to use and wear. I ran it for two hours and the battery was still going strong. Highly recommend.

Tired of bad marketing with 100,000 lumen... every few years they add an extra "0" with the same brightness. It is bright. It will suit your needs indoors excellently; a little bulky but you can mount on top of a cover. Battery indicator is non-existent when charging, and only shows one blue dot only if you turn it on. Going to get to test its waterproofing and battery life in the next few weeks, but the battery charge indicator is a bummer.*update* dropping it to 1 star. Will not charge nor work anymore. Used a known working cable, as well as known charged batteries.*update 2* seller shipped me a new headlamp, so kudos to customer support! It is a bit bulky, but that is the trade off for extra battery life (for those expecting a tiny headlamp). Just got a lemon is all, and got replaced pretty quick. Plenty bright indoor and outdoor. The output port is very handy for charging a phone or other devices.

Great value and no complaints. Super great quality- simple to use and very bright

I don't know much about measuring brightness or candelas or lumens or claims there to, but I do know that this lamp is incredibly bright, which is what I care about. I am frequently in the attic or under a house or just doing something in the dark and this performs exceptionally well. I like the adjustable diameter of the beam and the two mode brightness level. I have no use for the blinking light feature and have not bothered with the hand wave activation feature. It is a bit heavy and bulky, but fair enough, thats the trade off for a strong light that last several hours on a charge. The top of the head band helps with the weight. It comes with hardhat clips too. It does take several hours to return it to a full charge after it has been used for a few hours but this isn't an issue with the way I use it. Oh, by the way, be careful using this light around others as you will blast their eyes out if you look directly at them with the lamp on.

The media could not be loaded. This headlamp is bright. It had a high and low setting and an emergency flashing. You can also focus by pulling the lamp circle forward. The light bulb does gets warm and it is a bit heavy compared to smaller headlamps. I wear this on my hard hat so it really doesnt bother me. My coworkers joke that my headlamp gives them a sun burn because of how bright it is. Well worth the $$$. Battery last me for the entire night. I charge it everyday. Regardless you can remove the batteries and buy better ones if needed. They work fine for me.

I received a replacement light and wanted to give it time to ensure it works okay. It's been over a couple months and I've used the light for various projects. The replacement works consistently, so I guess I just got a bad one initially- things happen. The light is extremely bright and easy to use.Highly recommend.Old- At first this light worked really well. It was much brighter than any headlight I've ever owned. After two/three weeks it started acting up to the point it was unusable. The light would turn on but then randomly turn off. Sometimes it would stay on for 2 minutes but eventually turn off. Other times it would be on steady mode, blink a couple times and then turn off. The batteries were fully charged and still that did not help. Also I could not detect a short in the wiring. Nothing made sense. I could not find any means to contact the vendor to discuss, so it was returned.

I used this light for dog walks in the evening. The light was nice fully functional but after second or third use the head strap came undone. When I put the strap back it kept falling apart while on my head. Too heavy bulky and fell apart while try to juggle 2 dogs. Too late to return so will try something else.

I use a headlamp most of the day when working on machines. This was excellent out of the box. But I could not charge it. I bought another identical unit, assuming it was a defect. The same problem: it would not charge. Emailed seller. They explained that you cannot charge USB-C to USB-C. You must charge USB to USB-C. The problem is solved, and I am glad to have a second unit as a backup. It is heavy because it has three batteries versus one or two. However, you can run it on just one battery to reduce weight. I would give it a 5 star if it charged USB-C to USB-C and reduced my charging cord inventory.
