Thats a slippery slope you are walking mate......you start off experimenting,buy 1, then 3 and then before you know it you are joining candlepower forum, and spending all your play money on new and fancy emitters, and starting to use strange language like CREE, and Lumens, before you know it you will be debating the benefits of 18650 batteries vs CR123
there are some bargains to be had, there is also some crap.............a bit like Chinese camper trailers really
I have a Led Lenser H7 head torch as my kick around camp head torch, its not too bad, about 170 lumens but variable output and focus, a good quality all rounder, but not as robust as some others.
My goto torch for when I am in serious country, eg hunting in the Vic High Country and walking out after dark is a
spark ST6 at 500 lumens it is sensational, and fully water proof machined aluminum case.
Petzle are good gear but pretty dated designs and their performance is pretty ordinary compared to something like the ST6
hand held torches wolfeyes are worth a look but some serious $$
And yeah I am a bit of a torch nerd
