We have propane, kerosine, oil lanterns, oil lamps and candles. They all have different benefits. I like candles in the bug out bag. I like oil lamps the best. We use oil in the oil lanterns too. You can get these at walmart for 5.00. This oil will not have fumes as other fuels do. Oil lanterns have wicks at walmart for cheap to stock up on. We use propane in camping stove, lantern, heater,etc. This is versatile because you can move non spillable fuel to and from each unit. We have learned that the kerosine has fumes and spills, so we are moving from using it. So we stockpile for propane, oil for lamps and lanterns along with wicks. I notice that many have too many kinds of fuel and devices and cannot concentrate the stocking of fuel and wicks adequately. Interesting subject......thanks.
