Before it goes in your pocket
Good questions.
Straight answers.
Why make a flashlight flat?
The 0.63-inch profile carries more like a pocket knife than a conventional tube flashlight. It also resists rolling off a work surface.
Can it charge with USB-C?
Yes. ArkPro Ultra supports direct USB-C charging and Olight’s magnetic MCC charging system.
Can it work hands-free?
Yes. Its magnetic tail and two-way clip let you place or attach the light while keeping both hands on the job.
Is it waterproof?
Olight rates it IPX7 for rain, splashes, and temporary immersion.
