I have not used kerosene lanterns in years.
Before electricity (Rural Electric Administration)
came to my Uncle's farm, he used kerosene lanterns.
In summer they generate noticeable and unwanted heat.

My Uncle's lanterns were pressurized and very efficient,
but for camping and survival purposes, the wick type
might be better. Lehman's has some good prices.

It is good to have options. And sometimes the heat that is
generated is an advantage; it could keep valuable equipment
and supplies from freezing. Note that most of the lanterns
will burn at least 8 hours on one filling.
