Sorry again bestcounsel, have to answer to jar3ds
jar3ds, I think You got me wrong.
OK, I absolutely dislike the optical appearance of the Apex, and like the Eos, but think You did not get my important points.
actually the Apex has just one useable runtime, the both 9 hour light levels.
A bright superpower (under 2 hours) throw headlamp using normal AA batts just makes no sense; give the light a normal headlamp beam (like NX05, or Fraen LP, or ...)
now runtime/brightness:
A 4 AA (NiMh) batt light running for 3+ hours at MAX, is a Lux III running at full power (some losses already included). So that would make a good full power level.
double of that (6-8 h) as 2nd light level and something about 15-20 hours (3rd), should both still be good for walking.
Then a very low (30+ hours) for "navigating", reading, ... at close distance, to complement the 4-level-headlamp.
That would be the perfect headlamp, by now only available for modders.
PS: I think the lower levels are much more importatn, than what most ppl think. The ususal hiker uses something like a Zipka or whatever. They dont like to see nothing, when Your MUCH stronger light is around.
@bestcounsel: for headlamp chores You will only need low light, for property checks anything, but no headlamp. Might make You an enlighted target.
