I keep an Olight ArkFlex in my toolkit. I use it in two ways: 1) as a work light – to illuminate the nearby area in which I'll be working, and 2) when I go walking before sunrise or after sunset, clipped to my hat. With the Flexhead, magnetic tail and double-bend clip, it is extremely versatile. But also now discontinued.
So naturally, I was interested in checking out the new Nitecore EDC09. I noticed the obvious advantages over the ArkFlex – USB-C charging and multi-color tint with a high CRI option. I just read the ZeroAIr review of the EDC09, and have drawn some conclusions based on the following observations.
- The ArkFlex is much floodier (2 candela per lumen vs. 5 for the Nitecore, Nitecore throws 40% farther).
- The ArkFlex usable medium lasts much longer (7 hours at 95 lumens vs. 3 hours at 120 warm /150 cool lumens for the Nitecore) as does low mode (38 hours at 15 lumens vs. 13 hours at 30 warm/50 cool lumens for the Nitecore).
- The ArkFlex is about half an ounce lighter with a better waterproof rating (IPX7 vs IPX6) but worse drop rating (1M vs 2M).
My conclusions:
- For my particular uses, the ArkFlex is better. I don't need throw in my work light or cap walking light. The longer run times on medium and low, albeit at less power, make the ArkFlex a better dedicated work light. The lighter weight and better water rating make it a better cap walking light.
- For general EDC including the occasional small work tasks, the EDC09 is better. But here, it is competing against a ton of other great EDC lights.
- Personally, I don't need to replace my ArkFlex for my uses, and I already have great EDC lights. The EDC09 is in a bit of a "no man's land" for me.
- If you don't have an Arkflex and want an occasional work light, the EDC09 will work fine for you and can be used for other purposes.

Sadly the Arkflex is not available anymore. At least as far as I know. But check out the Fenix WT25R.
