Strengths & Trade-offs
Strengths
- At 4,600 lumens on turbo, this flashlight produces an enormous amount of light — enough to illuminate an entire backyard or trail with ease.
- Built-in USB-C charging eliminates the need for a separate charger. Just plug in with a standard cable — the same one you use for your phone.
- IPX8 submersion rating means this light can handle being fully submerged in water — a must-have for outdoor, tactical, and maritime applications.
- The moonlight mode (sub-1 lumen) is perfect for checking maps at night, reading in a tent, or navigating without destroying your dark-adapted vision.
- A magnetic tailcap lets you stick this light to any ferrous surface for hands-free illumination — great for working under a car hood or in electrical panels.
Trade-offs
- At 223g, this is a heavier light — acceptable for duty use or a pack, but too heavy for lightweight EDC pocket carry.
