Good friend of mine recently replaced her Petzl Bindi headtorch, because the battery gave up and was not able to provide required time of illumination.

So I decided to let mine undergo an empirical test.

Manufacturer specification

  • Brightness: 200 lumens (ANSI/PLATO FL 1)
  • Weight: 35 g
  • Beam pattern: Flood
  • Energy: 680 mAh rechargeable battery
  • Certification(s): CE, UKCA
  • Watertightness: IPX4 (weather-resistant)
Lighting Color Lighting Levels Brightness Distance Burn Time Reserve Lighting
White MAX BURN TIME 6 lm 6 m 50 h -
STANDARD 100 lm 23 m 3 h 1.5 h
MAX POWER 200 lm 36 m 2 h 1.5 h
Red Continuous 1 lm 2.5 m 33 h -
Strobe Visible at 400 m 200 h -

My measurements

For practical, real-life limitations I did not check all the manufacturer claimed parameters. My headtorch was bought on 2022-05-19, so at the time of writting this it celebrated pretty much exactly one year.

Lighting Color Lighting Levels Burn Time
White MAX BURN TIME ~ 82 h 00 min
STANDARD 3 h 00 min
MAX POWER 2 h 20 min

Disclaimer: The headtorch was not used extensively during the year. I needed to use it during few runs, climbs and cave explorations, but that was it.

Conclusion

I am absolutely in love with this headtorch. It weights nothing. Can be charged over USB (albeit older micro-USB). Has an incredible battery life on the lowest setting. Does not have to be ashamed when it comes to light beam strength when needed. Can automatically lower the brightness when the battery is running low.

Even after one year of usage the battery life is still very good. Not sure how to explain that I measured more than what Petzl shows on their website, but that's good news from my perspective. All and all very much a worth it purchase.
