This is my public service announcement assuming I'm not the last person on the planet to learn of these high powered headlights. When shooting the Super Bloom in California last year, I found the well reviewed headlight I bought was way too dim to walk desert trails to get to a sunrise spot.
So, I started some serious research and came across a number of really bright and rather pricey headlights. This particular unit is a Nitecore HC30. It's powered by what looks like an oversized AA battery. The battery is an 18650 and is the same battery used by Tesla in at least some of its battery packs to power its automobiles. Several thousand cells are in each battery pack, of course.
In addition, the headlight has a very bright LED. Also, one button cycles through brightness levels so, it's easy to use. There are a number of other brands and units with different features but the simplicity of this one appealed to me.
We used our headlights after the sunset shoot on Mt. Rainier as well as on the trail up First Burroughs Mountain for sunrise. You can see every root and rock waiting to trip you up and still have your hands free for camera gear. I like it!
