I gew up using ANY Petzl (and a few other lights/makers mentionned here) lights, we even built our own ones sometimes
but when I got my 1st Zebralight, EVERY "typical" headlamp makers products got screwed.
the argument that "serious" outdoor ppl use this or that has no value at all, simply because "the typical" of them has less knowledge of lights than a newborn baby.
And the traditional makers have even less clue on how to build a LED flashlight, than the users who are still getting that overpriced plastic crap, running on silly energy sources.
--> get Zebralight, Armytrek, Fenix, ...
(...based on the batteries You use in Your other gear)
Regular users are not flashoholics and have other priorities. Weight, runtime, helmet compatibility and running on the same 'silly energy source' batteries as other gear like GPS and avalanch beacons. Rarely do I need a lot of lumens. Why would anybody need 150+ lumens?
Petzl, PT, black diamond make lights for regular users and they do it well. Sure Fenix, Armytrek and Zebras look nice and have nice specs. But actually outdoor use? Those alluminium headlights like the zebra are not suitable for users in the serieus outdoors. Aluminium conducts to well in the cold and are not very glove friendly. It's either flood, spot or a add on defuser which outdoor people probably loose quickly. All regular outdoor brands offer lights which combines flood and spot options in one headlight.
I have never had one of these regular brands fail on me with giving light. Just the plastic battery latch cracks after years of abuse because i use them so much. And i never understood the 'durabilbity' issue with flashoholics. Somehow durability is so importent, but flasoholic's buy a new light every other few weeks.
There is a market for all kinds of type of headlights. If it aint your type of market, it does not mean it's no good.
