Specification Profile
Relative dimensions at a glance
Each axis is normalized against the largest raw value among the products in this comparison. Farther outward means a larger value, not necessarily a better result. Axes with an unverified value are omitted.
✓High brightness and good beam quality✓Versatile mounting options including magnetic tail and pocket clip✓High color rendering index reducing eye strain✓Solid build quality with aircraft-grade aluminum body
✓High maximum brightness at 5000 lumens✓Stable output with boost driver✓Convenient USB-C charging with powerbank capability✓Good build quality with flat tailcap for stable tailstanding✓No PWM (pulse-width modulation) in light output
Common complaints
⚠Magnet not very strong on curved metal surfaces⚠Headband attachment not very comfortable for switching between handheld and headlamp use⚠Pocket clip is not very stiff and less comfortable to clip onto pockets
⚠Can turn off under strong vibrations due to brass button contact design⚠Some color tint shift in beam⚠Limited thermal regulation leading to output ramping on turbo mode
