That reminds of how I first came across CPF - a link on the (excellent) onebag.com website.
At that time, the author recommend the 2nd-gen Inova X1 (a good choice at the time). I see he has continued to update the suggestion - he went through a few Fenix lights, now recommends the 4Sevens Quarks:

He was certainly bang on with his description of this place.
I've long been a prononent of the carry-on only travel method. Harder now obviously, but still doable. Once did two weeks in the
costa rican rainforest with a single bag. Also managed it for business travel - did two weeks across 3 cities in the US on business travel (with 2 sport jackets, one on me and one in my carry-on, so no one caught on!).
EDIT: Ha, that's too funny - I see the flashlight page on onebag.com actually has a link to my
Mini tint comparison review. Small world, since that page originally let me here!
