We have used other head lamps in the past and this is by far SUPREME.
Durability, brightness and battery life far exceed the other products.
Highpower for a small light.

I was one that would say, meh head lamps are gimmicks. After working in my attic installing Cameras I'm sold. Keep in mind also had a Neutron 2C V3 another AMAZING light. But this made life easier. I recommend. And they stand behind the products! The AA and adjustable light output sold me.
Headlamp is a Shining Star

Purchased the ThruNite TH20 as a replacement bushcraft/camping headlamp. What I first noticed was the price which was very reasonable compared to other comparable headlamps however, the fact that this runs on a single Double A battery and has varied light settings complete this rugged package for me.
One of the best on Planet Earth

I have lived off grid for over 8 years and headlamps are main source of lighting so I have tried many headlamps. The ThruNite TH20 is now my number one headlamp. For MOST of your lighting needs the lowest setting is enough and this greatly extends battery life. Going with AA battery use is a no-brainer. AA usually cost same as AAA and have three times the power capacity. Single AA run-time is then about the same as a 3 AAA headlamp. There is also the option of 14500 Li-Ion battery use. Wearing comfort is a BIG factor when using a headlamp for 8 hours or more a day and the ThruNite TH20 is very comfortable to wear for hours at a time. A 18650 battery headlamp will give you longer run-time but is not nearly as comfortable as a a single AA battery headlamp. One feature I VERY much like is when adjusting level you can go either up or down by just releasing button then holding again. You do NOT have to go up then down or down then up. Also like the SOS feature. You get plenty of heads-up when battery is getting low. This is my second purchase as I gave first one to my son as a gift. Build quality looks good and am expecting to use for many years. There are many user reviews you can watch on YouTube as well and they all seem to share my enthusiasm.

I love this light. Good, clean white light using a single AA battery. Great for backpacking!
Can't be beat!

Purchased neutral white. UI is the easiest to learn and use. Battery disconnects with 1/4 turn of end cap. Comes on to last light level even after battery is disconnected, UI appears to be non-volatile. Lots of light from (1) AA. Complaints by some about green spectrum for me are unfounded, not an issue at all.
Perfect head torch. Strong, comfortable, reliable.

I love it! I wear it everyday at work, at home, At the cottage and while camping.
TH 20 Headlamp review
Posted by Unknown on 26th Oct 2017
Best headlamp at this pricepoint.Only one AA battery or akku,aluminium housing,small size,dimmable,waterresistant,durable,leightweight.Since I bought it use it every day.
Posted by Derek Johnson on 27th Jul 2017
Its was for a friend and hes pleased..
Very good, some points for improvement.
Posted by Artiom Kapitanov on 16th Jun 2017
I have this head lamp for 4 month now, use it almost daily. All in all, love it.
BUT! the rubberband that goes around the head is started to get "wavy" like the cheap ones. That is not cool. Instead of spending on putting your brand name on it get a good quality, pure black one. There is a logo on a lamp, dont over do it.
Second, more of a sugestion. A little pouch/carrying case for it would be nice...
I will replace the band for my own I guess...
Its a good product. I Recomend it.

This is the most perfect headlamp I have ever used. I is very comfortable and has plenty of power for any task I need it for. I love the feature where you hold the on/off switch and stop when you reach the brightness you desire...awesome
Tiny,ultralight and just beautiful
Posted by Roy on 15th Mar 2017
Just heading up is so tiny and light that it fits in your front pocket without the bulge.The best part is that you can use a double AA battery. This headlamp uses a commend day battery. I carry this everywhere in my backpack, I highly recommend
Good AA headlamp
Posted by Tom on 2nd Mar 2017
Powerful as for an AA, solid, durable, with a cool, gradual brightness interface. Just, as for an AA light it could be a tad lighter. This is not a thrower, but it is well balanced anyway.

I absolutely love this headlamp!! It's perfect for me when I take the dogs out at night. I have MS and I have to use a cane. I also like to keep my pistol on me at all times too for protection. I keep my little dog on a leash so you can see just with the leash and cane my hands are full, add my weapon and a flashlight and I'd need to be an octopus! With this lightweight, perfectly bright headlamp my hands can be free. I can keep my weapon on my hip and if there's an issue I can release my dog and cane and be able to safely see and protect myself. (Don't worry, I can stand without my cane, long enough to protect myself and get to safety.) This little headlamp is a real lifesaver for me and I'm super thankful to the folks at ThruNite for making such an quality product!!
