A couple of months ago I wrote an article on the ThruNiteTH10 headlamp, and I followed up with a YouTube video where I shared some “On The Trail” experiences with the lamp. Since that time, ThruNite sent me their new headlamp, the TH20.
Here are some initial thoughts and specs on it.
Quality. ThruNite makes quality gear. Just like the TH10, the TH20 is constructed with the same aircraft grade aluminum. I will never have to worry about breaking this headlamp after an accidental drop.
Weight. When I first opened the TH10, the weight of the lamp stood out (as compared to my Petzel). That has been taken care of…ThruNite shaved a whopping 27% off the TH10 with the TH20 (132g vs 96g). While the TH20 is still heavier than my Petzel, it is much more comparable, just 54 grams (or 1.9 ounces) separates the two now. This is a considerable step in the right, AKA light, direction.
Battery. The TH20 will operate on either one Li-ion 14500 750mAh battery or a single AA battery. The choice to be able to use a commonly found AA will come in handy in certain circumstances. However, there is one downside to using a AA as opposed to the 14500, lumen output. The max lumen output with the 14500 is 520 as compared to 250 lumens with a AA.
Lumens. Even though lighter, the TH20 still produces a massive 520 lumens on turbo (with a 14500 battery). It is a versatile lamp as there are four modes that follow; Turbo (AA) at 250, Infinity High (AA) at 230, Infinity Low (AA) at 1.6, and all the way down to 0.3 lumens in firefly mode. While testing my TH10 on a couple of night hikes I found myself using its 172 lumen setting most often and I believe I would simply adjust to the 230 lumen setting with the TH20.
Overall. Even though I haven’t taken my new TH20 on a trip yet, that hasn’t stopped me from growing fond of it. There are three primary reasons I am looking forward to using my TH20 on the trail.
First, brightness. This is the reason I was drawn to the TH10 in the first place. I wanted the ability to brighten up the trail when on a night hike. I have never heard anyone say, “My flashlight is too bright.” With an operating lumen range from 0.3 up to 520, I’m not going to be losing out on any power with the TH20.
Next, comfort (especially with the reduced weight). I sleep wearing my headlamp on my head all night. Always have, always will. While the TH20 doesn’t have the over the top strap on the headband, I can’t imagine it being any less comfortable than the TH10.
Lastly, confidence in the battery. When I first went to the TH10 and the required 18650, I was unsure. I was unsure due to my lack of education on the power and longevity of any battery other than the standard AAA, AA, C, D (and so on). Now that I am educated, I'm a convert of the “non-typical” battery options available. I was completely impressed with the 18650, and from what I have researched about the 14500, I will be pleased with that as well.
Time to start planning a trip with my new TH20, my new lighter light!
I hope to see you on the trail,
