Carbon monoxide from canister lanterns

Does anybody know if the small canister lanterns (for example the snowpeak lantern that runs off of a canister) is safe for use in a ventilated tent?

I was thinking about one of these for winter use in a hex 3 shelter that has vents at the top plus open bottom and it might be running for an hour or two. I don't recall reading anywhere if these give off an unsafe amount of carbon monoxide. Also wondering how well they would work at temps near freezing or slightly below.

Thanks!

That's a good question Daniel. From articles here on CO emissions, it seems that the geometry of the burner head as well as distance to the cookpot has a lot to do with emission rate. A lantern would have very different geometry and the question is, "Does the flame have the opportunity to complete the combustion cycle?" Hopefully, Roger or some other stove experts that we are lucky enough to have on this site can shed some light (no pun intended) on this question.

Your post did get me to thinking about candles as an alternative light source. They are lightweight and long lasting and don't use up your fuel for cooking. As to CO emissions, I found this article below, that addresses it. The candle idea sounds relatively safe. BTW, I too have a Hex 3 that I use for winter camping. Cheers.

I have to say 'Dunno'. Never tested a lantern. Maybe later on.
