A start. The Aladdin mantle lamps were designed as a replacement for the older wick lamps. Since Aladdin lamps do not flicker they provide an even light and when used with a shade they are superior to most other lamps for reading or general lighting within a home. OTOH Coleman and all other pressurized high out put lamps also put out a very bright light and in this process (no free lunch) they also produce a considerable amount of heat, all depends on their CP/BTU. Heat might be good in a cold cabin but any who have sat around a Coleman in the aftermath of Hurricane can tell you how much heat was added to the 100% humidity. OTOH, Petomax and others have a shield that converts those Lanterns into heaters. I have at least one of each on the poll list. Each one has a purpose and a place in our preps. What ever you purchase be sure of a parts availability unless you just want a Fireplace Mantle Decoration. Feel free to suggest your needs/wants and the reasons.
