In addition to charging, the SC21 Pro is also a backup flashlight with illuminated switch button, and also works as spare battery carrier. It even has a magnet ;-)
Anduril UI allows me to set the SC21 Pro to 24 steps similar to HDS, with similar maximum of 200 Lumens.. Holding the button down, will ramp through all 24 steps, similar to HDS Rotary. Or it can be set to 12 steps, like the Tactical Rotary, or even to just 4 steps, like a clicky.
Anduril also has similar options as HDS, to always turn on at the same output, or at the last used output. It also has instant access to maximum, like HDS..
For this task I use a Black Diamond Moji+mini Lantern. It is AAA powered, and if you like built in batteries the Moji R+ is even smaller.
I had such kind of lantern with me in Africa to fight the darkness, and it was perfect with the Moji+. No reason to fear the darkness.
