I have used the coleman stove in tents north of 60 in winter and been warmer than in a house in Toronto.
I have been looking for a hand pump mantle light like th kind that were used on the farm when I was a child, The gas cannisters that power the mantle lanterns sold in the hardware store are considered hazardous household waste when empty and so have to be taken to the collection station along with old florescent tubes and those funny spiral ones.
I use a mantle light for outdoors and for emergency lighting in the event of a power failure.
