I have no idea who that guy is in Florida but he has to be one smart fellow.
All I know for sure is that after many years , to many to mention , I have been using one of the candle lanterns and it has always worked for me. A light in the night whenever it is needed. They even make a reflector for it so all the light is focused downward. For some reason I have no idea where the one for mine is , it's somewhere around here.
It is sort of the old fashion way of having some camping light in your tent and best of all , it is one piece of camping equipment that does not require batteries.
The investment in one is pretty good , I think I paid around $15.00 for mine a good 30 years or more ago and it is still like new. The brass is tarnished ( discolored) and needs polishing but by leaving it natural it adds more character to it.
It has been on a lot of trips here in the States and even into Canada with me. I keep it in a pile Pouch ( a small stuff sack made for it ) when it is not in use and /or when packed up.
Yes .... I consider it a valuable piece of camping equipment and as I said , it has been with me for a long time. In buggy situations you can have Citronella Candles to use in it , from Campmor and they are like the rest , a 3 pack.
The little lantern can be hung in the tent and when lit it provides a little extra warmth on a cold night while you sit there writing in your trip journal. The way it is designed it does not drip hot wax on anything , heck it does not drip wax at all , just burns every bit of it. Plus there is no exposed flame to worry about burning your tent down.
Now that I am going to be using a single walled tent , at times , they say that condensation builds up in them really good from a persons breath if the tent is not well ventilated , as in a hard , overnight , rain. I was reading where a guy hung one of the candle lanterns in his tent in the morning just before daylight. He would light it and when all his stuff was packed it had removed most of the condensation from the inside of his tent. Remember this are single persons ( solo) tents and not that large ( rather small ) plus they are the quick drying silicon nylon material.
