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!!

My wife and I each have the TH20 and Love Them! When you need light And both hands... This is the light you need. Multiple brightness levels, great battery life and... Dependable! All on a single AA battery!
We even bought one for a friend!
Small lite, Big performance

I saw this on a youtube outdoor winter camping video. It seemed very useful and not very big, so I ordered one.
Great price, very floody, lasts quite a while, all from just a AA.

Lightweight and Bright
Posted by Bill H. on 30th Oct 2016
It really is hard to find anything to complain about with this light.
It is plenty bright using just a AA battery.(apparently even brighter with a 14500 battery)
It puts out a nice broad pattern that works nicely for a headlamp.
It is also very light and comfortable to wear.
While I really do like my headlights to have a red light function with this light's lowest mode so far I have not missed the red light.
I feel it is priced realistically as well... Not super cheap but not $100 either.
Well built, small, light, comfortable, functional light for the money.
If I had to make any suggestions I would say to go with the natural white version.
In my opinion it really is the most useful color option and I am not really sure why ThruNite would take the time to offer the cool white version.
I can't find a single thing to complain about with this light.
Compact AA Headlamp for people seeking great gear.

I found the form factor to be great. One button operates on/off and variable brightness from firefly to fully bright. Simply unscrew the tailcap to lock out light in your pack. I have used with both the 14500 and AA batteries. Either will provide more than enough light to explore the night. I bought a second one I liked it so much.
Great bit of kit

Had my th20 3 weeks ago I've used it every day and can't fault it's quality and performance I have and will recommend your products to friends
Excellent except the head strap slips.
Posted by Unknown on 29th Sep 2016
It is a fantastic easy to control intuitive light. My only beef is that without a top strap the thing tends to either slip down or slip up... on a head with no hair it wouldn't be an issue.
Great piece of gear.

Excellent headlamp, priced right. Brighter than I thought it would be. Light output is more than you would think for the size.
Posted by Unknown on 19th Aug 2016
This is an excellent light I use it doing morning and evenng chores. I love that my hands are free to do whatever needs doing.
Very Pleased with the TH20
Posted by Andrew on 13th Jun 2016
Never having owned a headlight before, I don't have anything to compare this one to. Having said that, I really like the TH20. The infinitely adjustable brightness is a big plus, the construction is sturdy and straightforward, the tilt feature works great, the stretchable headband allows a good fit, and the price is very reasonable. Similarly to one of the other reviewers, I ordered the cool white LED but the tint is decidedly warm and yellowish---not a dealbreaker but ThruNite needs to pay attention to this.
I use the TH20 for close-up work on small items, and it is a huge help in putting plenty of handsfree light exactly where I need it. I am very happy with this purchase.
