price aside, first estimate the possible locations at the destination that may require the utilization of a light, then approximate a ball park runtime. this will give you something to work with in terms of bringing spare cells.
For long runtime and mimizing battery changes would probably go with the E2L new two stage KX2. [I own the single stage KX2 and I find the output pattern to be more useful than any other LED+optics lights I have]. Its not horribly expensive, but it will cost you a bit.
Something low profile usually minimizes the chance of it being stolen from onlooker's interest, I prefer a 2xcr123A size but thats a user's preference.
Instead of carrying an array of different lights, traveling usually consists of rudimentary components where I have kept at 3 lights maximum, unless of course you have accompanying family, bring a one light for each and make sure they know how to use it. :huh:
I used to carry the aviator but I found out it eats up cells pretty quick especially when you use the xenon function intermittently:green:
Uber high powered or multifunctions also tend to arouse interest...especially when your traveling to Asian countries.
heres my ideal lights for traveling, I selected these because they fit my needs/criterias, they don't necessarily able to mee yours
Long runtime/non-expendable:
E2L-CREE 2 stage,
inova X5
Cheap/Expendable:
Dorcy 1 watt [cr123A version],
Pak-lite basic [$10 each, runs basically forever, design makes it interently water resistant.
heres my rule of thumb, for a week long trip: bright at least one set of spare cells for every light you have. For a month long trip, bring at least 2 sets of spares for the lights you think you will need the most. as for longer tripes spanning more than 3 months? I dunno. I dont have that kind of privilege to go vacationing without income. :nana:
Also, don't leave all your eggs in one basket:thumbsup:
