In this video I put three of Olight’s top-rated EDC flashlights head-to-head: the ArkPro Ultra, Arkfeld Pro, and the ArkPro. I break down the physical differences first—size, weight, packaging, and the little design details that matter day-to-day. The Arkfeld Pro is the smallest (4.72 in, 3.92 oz), the ArkPro is slightly longer (4.88 in, 4.05 oz), and the ArkPro Ultra is the heaviest (4.23 oz) but the same length as the ArkPro. I also go over the controls like the mode dial, battery LEDs, and the bigger clip on the ArkPro series. Then I get into specs and features: pricing (about $100/$110/$130 retail), beam distance, max brightness, and battery life. The Arkfeld Pro tops out at 1,300 lumens with a 334 ft beam and a 1,500 mAh battery, while the ArkPro and ArkPro Ultra jump to 672 ft beam distance with 1,500 and 1,700 lumens, plus a 2,000 mAh battery for up to about two weeks max runtime. Feature-wise, the ArkPro series gives you more functionality—UV with two levels, flood + a dedicated spotlight, plus a side laser button—while the Arkfeld Pro keeps it simpler with flashlight/laser/UV. Finally, I take all three outside on turbo mode (with a fence about 100 ft away) and the winner for me is the ArkPro Ultra. Those extra 200 lumens are noticeable, and the O-aluminum build (claimed 1.73x stronger) makes it my pick for long-term everyday carry.
