Question about Petzl Actik Core

At full power (I have never used this, much too bright in my opinion) this is correct in my estimation. In normal mode with the normal Petzl battery I get by for 7-8 hours or more. (Estimated, no guarantee)

The manufacturer says the following (different modes indicated with lumens (lm) and range (m)):

6lm (8m) = 130h
100lm (45m) = 8h
450lm (90m) = 2h
(red light: 2lm (5m) =60h)
(flashing light visible at 700m = 400h)

I hope I could answer your question.
