I'm interested in some feedback before I make the decision between something like a Zebralight H31 vs small flashlights (ITP A series, Maratac).
First question is on lighting/lumens: How many needed for trail(obvioulsy at night), off-trail, and rough terrain like class 3? This helps clarify my decision for what I need for a "medium setting" – many lights will provide enough on high, but not for the required duration, and without overheating.
Secondly, how secure is the clipped flashlight? what are the limitations on activity (running, light climbing, etc.).
For thoes who went from a headlamp to a clipped flashlight, how is vertical adjustability? Obviously is is somewhat limited compared to a headlamp but how much of an issue is it? Do you need to buy a light with greater spill to accomodate the change? In short, I'm looking for user experience and the pros / cons from those who went from headlamp to clipped flashlight. Thanks!
