I found this on Amazon when I got curious if there were any such devices after writing my Coleman Lantern Review. REI has a Snow Peak (same people who made my titanium pot!) Canister Lantern for $75. Which is surprisingly expensive. Even the less expensive Amazon Option is pricy at $20 relative to the stove I picked up for $6. But I'll take $20 over $75, no questions asked. The reviews seem to indicate that it's as much a radiant heater as a lantern, which makes me think this might be more worthwhile in adverse conditions/colder weather than something I'd need on a summer hike. Unsurprisingly, it indicates they're a bit of a fuel hog too.
Probably not NECESSARY gear, but it'd be neat to have and try out at least. For now, I've got better things to drop $20 on. For now.
