Okay, after researching for a bit this morning, I believe I might have come up with a solution for using the Lotus in a cold, high altitude environment.
They make butane torch lighters specific for high altitude uses. The two that I've zeroed in on so far are:
Xikar Stratosphere, $22.50 and eligible for Amazon Prime.
Vector Stratos, $22 shipped (not Prime).
Both lighters are rated for use to 12,000'.
Regarding the cold factor, I will be keeping the lighter inside my jacket media pocket most likely. So I'm thinking body heat will keep it warm enough.
Reading one review:
"During recent cold weather here in Georgia I was able to test the Stratosphere outside in slightly more fitting conditions. The stratosphere performed flawlessly in the cold, and has performed flawlessly since I bought it. To further test its cold performance I stuck it in my freezer for two hours hours while I was out getting dinner. Not surprisingly, it didn’t light immediately after coming out of the freezer. However, it lit off at full performance within one minute of coming out of the freezer, and being held in my hand while I clicked the ignition switch every 3 to 5 seconds. This is impressive performance even for a higher end outdoors lighter. If one keeps the lighter in an interior jacket pocket or the like to prevent it from literally freezing when out in extreme cold I have no doubt the Xikar Stratosphere will perform in conditions when you absolutely need to start a fire or get a camp stove going. Previously I’ve tested this lighter in front of a box fan to simulate strong sustained wind, and it stays lit. I’ve even blown it out, which adds exhaled CO2 for further flame suppression. Because of the recessed jet and floating heat coil it immediately relights itself."
So I believe the altitude/cold issue can be resolved.
My next question is, how essential is the angled neck on the lighter? I was unable to find a high altitude lighter with an angled neck.
However, in two video reviews I watched, one person turns the Vector upside down very quickly without the lighter extinguishing. Here's the video in question (skip to 10s in):
In a video review for the Xikar, another person was keeping the Xikar lit while in a horizontal position. Like so (skip to 3min 30sec in):
What are people's opinions on these lighters working in my situation? Do nearly all torch lighters extinguish when held upside down? Perhaps I could make due with angling the Lotus halfway to meet the lighter if all else fails.
Any and all input is welcome and appreciated!
