Common praise
Extremely high maximum output and throwLong runtime on lower modesRobust build quality with premium materialsEasy one-handed operation via side electronic switchEffective thermal regulation and battery power indicatorsMultiple brightness levels and special modes like strobe and SOS
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
Heavier and larger compared to smaller EDC flashlightsHotspot tint with some yellowish corona noted in beamSide switch has small UI quirks such as mode skippingBezel can get damaged when dropped despite stainless steel material
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.
