5. Oil lanterns
These lights use fire and oil, the way that a grease lamp does. But being enclosed in glass – they're less of a fire hazard and more weatherproof. Oil lanterns can burn on kerosene, liquid paraffin, or lamp oil. They can also work with vegetable oils, but not as effectively. Just make sure you never put gasoline, white gas, Coleman fuel, lighter fluid, alcohol, paint thinner, or similar low-flash point liquid fuels in the tank – the lamp will blow up!
