How It Scores

Strengths & Trade-offs
Strengths
- Our algorithm rates this a 97.1/100 for value — meaning you're getting significantly more performance per dollar than most alternatives in its class.
Trade-offs
- 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.
- No mode memory — the light resets to a default mode on every power cycle instead of remembering your last brightness.
