Bought this for a nephew at summer camp but had to try it first. Glad I did! This thing is awesome. Look at the photos- the beam goes from really wide and bright to super focused very easily. The headgear is very adjustable and the battery sits on the back of your head, balancing the light up front. It’s all very clever and durable- it feels like it will last a long time. I’m really impressed with this thing! It even tells you what percentage battery you have left!

This headlamp is very comfortable and adjusts nicely to fit on your head. It comes with two large rechargeable batteries and has a very long run time between charges, and also charges very quickly. The light itself is super bright and can be focused in and out, and has a dim and flasher setting. On the back of your head sits the battery pack which has its own set of red lights which can also be set to flash. There is also a digital readout of your battery. This lamp is an amazing value and I highly recommend it!

Ill start out by saying its a solid 4.2 out of 5. My general dislikes out the way first, when utilizing work gloves the button feels a bit hard to press due to its small and compact nature, and i find that when i press and hold to turn it off, it randomly turns back on again which is easily remedied by pressing the on/off button one time. The second issue i find is mainly a slight bias thing, i guess i have some kind of preconcieved notion of how zoom functions on headlamps/flashlights work, and was disappointed by this headlamps seemingly "loose" zooming. Like its just too lubed up or something, it just zooms in and out *too* easily. Now that the dislikes are out of the way, everything i like about it, its cheap, waterproof to the rain(which is incredibly nice for work), its incredibly bright and very visable even in daylight conditions, provided you arent in literal direct sunlight, the charging port in the back comes with two very replacable and seemingly easy to find Lithium Batteries, and the ports themselves are a standard C-Type port to charge the batteries, and a USB-A port to utilize the batteries to charge something else! Its the first headlight i can confidently say, i can charge my phone with XD. All in all super duper worth it for the price i paid, and if for whatever reason it dies on me, im out 25$ and will more than likely buy a new one

Perfect fit and does the job perfectly. Has three different brightness levels including a flashing setting. Comes with two rechargeable batteries. Charging process is easy and straightforward as well.

I've used my fair share of random headlights and they seem to work fine. But WOW this has been game changer for me. I work on cars and often times my gloves are dirty and covered with dirt. Touching the on and off switch would result in my face getting dirty. Now with this head light it has a sensor on the side that you wave your hand next to it and it turns it on. I tested this outby sticking my head inside my washing machine. In the photo without the light it looks better but keep in mind its actually dark inside the washing machine. Using the headlight allows me to inspect the inside. I actually recommend this light for anyone who works with dirty hands.

If you need to do something on back yard or during the rosy at time this light will help you a lot.

It's a headache to wear, it's very heavy, and it gets hot. You can only hold it in your hand. I don't recommend buying it. The brightness is not as high as the advertised 150,000 LM

The 18650 batteries shipped with this light are 18mm diameter x 68mm length. My existing 18650 batteries (from two different manufactures) are 18mm diameter x 70mm length, and do not fit in the battery compartment of this light. I believe the 2mm difference in length is for the protection circuitry (located on cathode or button end), which seems to be the most popular (and safest) 18650 type. In other words, if you plan on using other batteries from those included, you will need to acquire unprotected batteries. I returned the light without using, as I don't want to maintain two 18650 battery types.

There is a problem with charging. I used the charging cable provided by the seller, but it didn't work. It's a defective product.

Used 3times and doesn’t cut on anymore even after charging batteries，Not recommended！
