Headlamp for 100M (12 hours in the darkness)
The Fenix HM65R-T V2.0 is kind of like the Salomon Adv Skin 12 of headlamps for long ultras. There are a whole bunch of reviews of this headlamp out there, so take a look.

alternatives to generators that don't make camp sound like a construction site?
What type of janky headlamp do you have that only lasts a few days? I do long multi-week backcountry canoe trips and my headlamp (Fenix HM65R) will easily last for 3 weeks of daily use.

Did someone figure out what brand/headlamp is true to their specs and which is the 'best' bang for buck?
https://zeroair.org/2021/05/26/fenix-hm65r-t-headlamp-review/ This review it shows medium (400 lumens) mode dropping to about 160 lumens in about 20 minutes. I didn't buy this headtorch because of these reviews. Mad how every single time i mention it's not a 400 lumen headtorch, more like mid 100 lu

Headlamps on a budget
Energizer headlamp, like $6 on sale. Got me through years of backpacking and the beginnings of my trail running. For the more expensive kind get the Fenix HM65R-T and a couple extra batteries.

What's your favorite flashlight/headlamp edc?
I use a Fenix HM65R. It was pricey at the time but damn is it a good headlamp. Going on 6 years old, pretty heavy usage since I'm on nights.

Fenix lights for caving
I'm moderately new and have been very happy with a Fenix HM65R as my main light and Sofrin H25S's as my backups. They aren't the absolute best on the market, but this has been my experience:Pros:- all are USB-C rechargeable and use 18650s- I've never had my Fenix die on me (or even get below half -

Official Q&A for Sunday, July 19, 2026
Can't you sent in the faulty one for a replacement? If it got got reviews it might have been just a dud. I use the Fenix HM65R-T V2.0 and it works great. A cheap battery powered Nitecore as a backup. I think Petzl Headlamps are the most popular brand next to Fenix.

Best Ultramarathon Lighting System 2026
This a great post - I do disagree with a few points: a) I don't think 150 lumens will be enough for a lot of people. For me, I prefer 300-400 lumens as a 54 year old guy who wears glasses. So I target a 5-6 hour runtime with one battery change during the night.b) I have the Fenix HM65R-T V2.0 and if

More comfortable headlamps?
I've got a fenix also and can vouch for the head strap mechanism. Works well. Do have to say that I had to replace my original though as it stopped working (I've got the HM65R-T) - under warrenty. My backup Black Diamond (Spot 400) is also great, comfy, reliable, though not as bright.

18650 Compatibility - Fenix
I never noticed before that my Fenix brand batteries that came with my headlamp are indeed a little shorter longer than the off-brand button top ones I bought separately. I will say I never had an issue with the off-brand batteries working for me. They seem to function just as well as the Fenix batt
