“The most versatile flashlight I've tested.”Popular Mechanics · Tested & reviewed ↗
O-ALUMINUM / ONYX BLACKA tool you want to touch and carry
Engineered flat. Built anything but.
The single-piece O-aluminum body is rated 1.73× harder than standard 6061 aluminum, yet carries at just 4.23 ounces.
01Dial by feel
A sculpted selector changes sources without hunting through modes.
02Charge your way
Use universal USB-C on the road or magnetic MCC at your station.
03Place the light
A magnetic tail and two-way clip turn any surface into a third hand.
The flashlight you actually carry
Ready before the problem is.
A pocket tool earns its place by being there. ArkPro Ultra stays slim, starts simply, and covers the unexpected from first look to close inspection.

Good questions. Straight answers.
Before it goes in your pocket.
Why is the body flat?
The 0.63-inch profile carries more like a pocket knife than a conventional tube flashlight. It resists rolling and keeps four light sources comfortable in a pocket.
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 pocket clip let you place or attach the light while keeping both hands on the job.
Is it waterproof?
Olight rates the ArkPro Ultra IPX7, meaning it is designed to handle rain, splashes, and temporary immersion.
