Burn timeis the duration of time the headlamp emits 0.25 lux at 2 meters. 0.25 lux is equivalent to the light of the full moon on a clear night.
2 Burn times shown here assume fresh batteries and use at one power setting for duration of test.
3 Alkaline batteries provide higher light output than NiCad or NiMH rechargeable batteries due to their higher voltage.
4 Please read user manual (see below).
