plus the idea on this little lamp as a heater is that it is so small it could fit in a jacket pocket or a BOB.

comment about the GAZ cylinders... used to use the little hand grenades with the Bunsen burner top... one day a student in a next door class unscrewed the burner and popped the legs off... the next door teacher brought the cylinder into my room spewing butane... luckily I was able to put it in my spark proof vent hood to clear the room... we immediately switched to units with a sealing Schrader valve

Sounds like you've found an inexpensive tent heater.

But flame + inside tent (meltable, if not directly flammable) + carbon monoxide + pressurized flammable gas + confined space with no rapid exit + apparatus and seals made in China (not the most safety-conscious manufacturing location!) + probably far away from medical help = I wouldn't do that myself.

Treat that setup with the utmost care, and stay safe.

You mean those 190gram puncture style canisters? Well I noticed that they have a flapper valve added to them on the inside. (often marked quite clearly on the outside) Too many accidents with those canisters. Now we have a valveless puncture canister with valve.... Also made them more expensive.

Different thread pattern on the cannisters


That's what I expected. I've got half a dozen left from an old gas table top grill and thought this would be a good alternative dual use if they fit.

P.S. The gaz canisters are an EN417 thread. The Coleman style cylinders are larger threads.

The Coleman-style cylinders stay fresh forever (it seems) as long as humidity doesn't rust the connection surfaces.

You could probably sell them on Kijiji/Craigslist and get at least half your money back. It's pretty obvious if they're full or not.

They also have the same thread as the standard hardware store propane torches (bernzomatic or other brands). Handy for soldering, fire lighting, unseizing rusted bolts, all sorts of stuff. Or making creme brulee if you have culinary inclinations.

My stash includes some that are at least ten (more like twenty years) old. I used some of them last month and they worked quite well. I stock both the Coleman cylinders and the smaller Lindal valve cylinders, pretty much standard for backpacking canister stoves.
