Read product detailsHow we compared them
We compared the current Olight ArkPro and ArkPro Ultra listings using stated flood and spotlight output, secondary light sources, runtime language, charging methods, dimensions, and weight. GadgetWunder has not measured brightness, beam distance, runtime, or durability. Mode-specific runtime claims are presented with their stated conditions instead of treated as directly equivalent.
What we left out
- Direct runtime winner ArkPro Ultra's 14-day claim is tied to moonlight mode, while ArkPro's 72-hour normalized runtime does not name a mode. Those figures do not support a fair runtime winner.
