Common praise
Impressive throw and tight beam for long distance spottingGood balance and lightweight for its sizeWell made with durable materials and finishReliable battery life with included 21700 batteryFast USB-C charging and power bank function
Very high max output of 4848 lumens with excellent long throw capability (1860 meters).Good build quality with hard anodized aluminum and tight threading.Simple and intuitive e-switch user interface with mode memory.Included accessories like shoulder strap and USB-C charger.No visible or audible PWM.Battery runtime up to approximately 5 hours and 16 minutes at firefly mode for 180 days.Good thermal performance with predictable step-down after 2 minutes on turbo.
Common complaints
Beam may be too focused for close-up tasks
No thermal regulation, causing step down due to heat after turbo mode.Threads are somewhat difficult to start or unscrew.Heats up significantly on turbo/high modes making prolonged handheld use uncomfortable.Limited retention options, some users find shoulder strap front mount flimsy.Low voltage protection is not fully clear; caution advised with unprotected cells.Large size and weight (over 600 grams without batteries) makes compact carry difficult.
