COSOOSRechargeable Headlamp Flashlight, Bright LED Headlamp,3500 Lumen 4-Mode Headlight,Waterproof, Zoomable Headlamp for Adults, Head Lamp for Hardhat, Li-ion Battery Included

I have had at least 9 other headlights in the past couple years all of which were in the same price range. This is the brightest and well designed light of them all. I am very impressed with the battery in that only one is required and it lasts as well as the lights I have had with two of these batteries. Having done some research into these batteries, very few companies put as much emphasis on designing and utilizing a safe, high quality battery got their headlight. I appreciate that a device is supplied that will hold 3 AAA batteries in place of the 18650 battery. It doubles the use time.I had a slight issue with the fit of this light so I contacted the seller. Their response was timely and the solution by far exceeded my expectations! I trust that this headlight will last a long time and when the time comes for a new one, I will come right back to Cosoos and purchase with confidence that I am getting the best value for my money and that in the unlikely event there is a problem, I will be taken care of by people who genuinely care.

Amazingly bright, one downfall.... It's so bright that if you shine it on anything close to you. You are blinded by your own reflection!Lasted 2 hours on a full charge at highest setting using the included battery.Love the ability to crank down the beam to a finely focused square or to open it up to a super bright circular pattern.Never had a headlight before so hard to compare but this one fits my little beany head well when I have trouble finding baseball caps that don't make me look like a little kidMaterial is middle grade but great quality for the price. The battery pack is not water proof and I would argue unlikely to be rain proof either. Use caution or only in dry weather.

What a great value for the money!Pros:The headlamp is very bright, and it stays that way for hours before needing to be recharged. The headlamp has lots of extras. Settings include bright, extra bright, super bright, and strobe, which is sure to get people's attention when necessary, even from far away. You can widen or narrow the light beam for floodlight or spotlight effects. It also has a red light in the back, which is included for your safety. Anyone approaching you in the dark and from behind will see the red light. The headlight angle is adjustable, which is nice and convenient. Finally, customer service is outstanding. It is fast, friendly, and effective. Cosoos really wants its customers to be happy customers. They followed up on my order to ensure timely delivery. Initially, I had a minor problem with the headlamp getting a tight fit onto my hardhat. Cosmos gave me a refund for the price of the helmet clips that I also purchased, and even asked for photos of my hardhat to see if they had an alternative solution for me. My problem was resolved to my total satisfaction. In fact, I was so happy that I also bought a battery charger from them so that I will always have fresh batteries on hand immediately whenever needed. The battery charger, like the headlamp, is awesome. I will be buying from Cosoos again.Cons:The headlamp is a little bit bulky, which takes some getting used to and is not helpful when working in tight spaces. To me, this is only a minor issue, which has improved somewhat after wearing the headlight for about a week. This minor issue is far outweighed by all of the other goodies that this headlamp offers, so I I'm quite happy with it overall.

I love this light! It is very bright and the price is right! I highly recommend it to anyone who lives in areas were there are power outages. I purchased mine because I live in Miami, FL, which is very prone to hurricanes. Once the power goes out, you really don't know when it will return. Having this light ensures that I'll be ready whenever it may occur. I also love the fact that besides having a lithium rechargeable battery, you can also use 3 AAA batteries to power the Headlamps/Flashlight! Additionally, their customer service is EXCELLENT! I didn't have any problems with the item, yet they were kind enough to do a follow-up with me via email and sent me 2 FREE lithium batteries! You just can't beat that sort of service! It was a pleasure dealing with this company and I will be exploring their site for other articles I may need.

This headlamp is extremely bright! It can light up my whole backyard and I have a huge back yard. It has many modes of brightness. I have a huge head and it is adjustable and fits perfect! I can't wait to go camping this summer with it. Plus it is great for power outages. It has a cool design and you can adjust the light angle up and down. I love the rechargeable batteries! No more buying batteries. You can use this headlamp with a hard hat, beanie, cap, on your bear head or whatever you have on your head! I recommend this headlamp to anyone who likes to see up close and far away in the dark! This product ROCKS!! It lights up my world literally!

I had a similar headlamp like this in the past and it stopped working. But this one from Cosoos is much higher quality. You can tell easily that it's better built. Examples: The charging port is standard micro USB, not a round plug. There's a charging light that turns green when it's done. The rear of the strap system has a pad for your head that the battery pack clips into. It's not just a rubber battery pack. The focus system on the main light has detents that click for each adjustment rather than a smooth screw. Overall, very pleased.

I have tried all the headlamps offered on Amazon. For a headlamp to have 5 lights, you would think it would be overpowered.... But in fact it is drastically under powered for light output. I found there are much better comply priced headlamps on Amazon that put out a lot of light for the same money and the makers back their product 100%I did not contact the seller or maker of the product, I was therly put out by is poor light quality and sent it back for a refund.I use headlamps everyday for work and need very dependable work light, these are Not the brightest for my work requirements.
