I have found the discount store hurricane and barn lamps to be quite functional. They are a bargain at about $10 a shot. They typically have just a narrow 1/2" wick that doesn't put out a huge amount of light but for general room or area lighting they work well and make a gallon of kerosene last a long time.

IMO they are several steps up from candles.

For detailed work, or reading I have used a single mantle propane lantern.
