As another poster mentioned, many people without power due to the snow storm. Winter power cuts need heat and light, both. For winter power cuts, fuel burning light sources are good to have.
Candles are the first thing most folks use. And careful is needed. Now and again some one will burn down a house, with candles too close to the curtains, papers, etc. On the rare moments I burn candles, I use short stable candles, and use a metal cake pan or heavy skillet as a base, less risk of burning down the home. Candles don't put out much light. Not too bad at night, when your eyes adjust after a while.
Wick lamps are also good. They can burn ultra pure or kerosene. There was some thing that went around about using mineral spirits paint thinner in a wick lamp. Yes, it does give off a lot of light. It is also a fire and explosion risk, far too flammable.
Mantle lanterns such as propane or Coleman fuel are very bright, and plenty enough to read or see what you're doing (staring at the dark TV screen).
