I also take good care of my gasoline lanterns, although they are not Coleman, they are something very similar from the Swiss Army. In a box there are two of them with spare parts and fuel, with one liter of gasoline you have around 200 watts of light for 8 hours and there is still nice heat. These lamp boxes are really very good and robust, except a little heavy, but if there is an emergency I have around 10 boxes to sell if I still have time for them.
