Overview
A PowerTap control on the housing switches the LED between full and dimmed output with a tap, and brightness memory brings back the last level you used. An integrated rechargeable battery powers it, a meter shows the charge left, and a red mode protects night vision.
Tap control and brightness memory make it quick to use in the dark, and the battery meter removes guesswork about charge. The listing pairs the integrated battery with a stray AAA entry, and gives one runtime without saying at which brightness it applies.
Who it's for
Campers, climbers and runners heading out for evening hours get a lamp that charges at home and reports what is left. Those spending days away from power should choose a model that takes spare cells.
Pros and cons
- Integrated rechargeable battery
- Battery meter tracks remaining runtime
- Red mode preserves night vision
- Brightness memory recalls last setting
- Battery fields conflict, AAA listed too
- Runtime brightness level not listed
- No swappable battery for long trips
- Mounting type field oddly says handlebar
Performance notes
Burn time depends on the brightness level chosen, because the integrated cell drains much faster at full output than dimmed. PowerTap and brightness memory let you drop to a lower level quickly, which stretches the charge, and the sealed housing protects the electronics in rain.
