Strengths & Trade-offs
Strengths
- At 4,720 lumens on turbo, this flashlight produces an enormous amount of light — enough to illuminate an entire backyard or trail with ease.
- IPX8 submersion rating means this light can handle being fully submerged in water — a must-have for outdoor, tactical, and maritime applications.
- Our algorithm rates this a 86.7/100 for value — meaning you're getting significantly more performance per dollar than most alternatives in its class.
- Impact-tested to 1.5 meters, this light is built to survive drops and rough handling in the field.
Trade-offs
- 195g puts this on the heavier side of pocket lights. Noticeable in a front pocket over extended carry.
- No electronic lockout feature means you'll need to physically lock out the tail cap (if possible) to prevent accidental activation.
- No pocket clip is included — you'll need a holster or aftermarket clip for secure carry.
- No built-in charging means you'll need a separate battery charger, adding cost and inconvenience for new users.
