I began using candle lanterns in the ’70s and “graduated to Candoil telescoping lamp oil lanterns in the mid ’80s. They burn longer than candle lanterns and give off a bit more heat and light.As far as I know the Candoil company no longer exists. Too bad, their products were high quality. Glad I still have mine. Great for power outages too.
For double wall tents and snow shelters lanterns are nice for the warmth and cheery light. Yes, you can read by them. I would not recommend leaving them on when you sleep for the fire danger in a tent but in a snow shelter they should be OK if not suspended over any gear. For a chilly morning they are very nice as well.
