How scoring works
The same GearScore engine the comparison pages use. This is the default weighting; open the full comparison to re-weight it around your trip.
GearScore blends published specs into one 0 to 100 number. Brightness is a "good enough" gate; weight and beam distance score on a sliding scale. Price is a lever presets turn on. Runtime, battery, and water rating are shown but not scored.
Customize on the full comparison →- Sufficiency
- Only needs to be good enough. Brightness works this way: bright enough for the job and the lamp is set, extra lumens add no points by default.
- Monotonic
- More (or less) is always better. Lighter beats heavier and a longer beam throw beats a shorter one, so they score on a sliding scale.
- Preference
- Battery type and water rating are personal preference, never scored. They only filter the list.
