- Compact and Bright
A high output headlamp with max output of 520 lumens in turbo mode powered by one Li-ion 14500 750mAh battery. The advanced design gives the TH20 a light weight of 76g (battery excluded). The TH20 can also use one common AA battery, which makes it a great choice for daily reading, camping and a tool light when you want your hands free.
- user-friendly UI
The logarithmic scale brightness adjustment system allows any brightness from 1.6 lumens to 250 lumens. Furthermore, the TH20 features a built-in SOS signaling mode which is important when roaming out in the wild or confronting dangerous situations.
- Durable and Tough
Unlike other light-weight headlamps which are made with plastic, the TH20 is made with aircraft grade aluminum which gives it exceptional durability and excellent heat dissipation allowing it to maintain high output for extended periods of time.

- Change modes

As usual Thrunite lights are of great quality and the spare parts that come with purchase are really great. This light is would be a perfect headlamp if not for the nasty green tint the light puts out. It is very un-natural and displeasing to the eye. Aside from this its made very well and comfortable, just dissapointed in the tint as my other Thrunites do not have this issue. I was going to purchase a T10 however am afraid of getting it with the same tint as this TH20.
I'm an avid camper and backpacker so have purchased and used so many headlamps over the years. I found this one reviewed on a Youtube video so on the recommendation of someone I have never met, I ordered one for myself and for a friend. I am impressed with the solid construction of the lamp itself and the quality of the headband. One reviewer stated his headband was sub par. I would definitely disagree. I feel like it's sturdier than any other headlamp headband I currently own. I am impressed with the brightness of the lamp and the ease of use. I also love that it turns back on at the brightness setting it was left at previously. I feel like I could go on more, but this is long enough. I think you get it by now... Oh, and by the way, I am ordering another one for my dad. This thing really rocks for doing anything - I've used it for my jewelry making projects, reading in the middle of the night and working on my Jeep. It's heavier than some of the other headlamps I have, but it is definitely worth it's weight in gold.
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.
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.
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.
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.
My little favorite headlamp.
Easy to use, versatile and conveniently using AA
OR 14500 Battery for hight output.
Also one of the best priced good headlamp on
I love this light. Good, clean white light using a single AA battery. Great for backpacking!
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.
