I went on a kerosene lantern kick a couple years ago. I ended up with two Den Haan solid brass oil burning lanterns. The price is quite high, about $350 for the pair. They use a flat wick that is twisted into a circle at the top of the burner. (If that makes any sense.) They are much brighter than the Wal-mart varieties, and being solid brass I expect them to outlive me. The smaller of the two, Den Haan berth lamp, is mounted on a gimbal, allowing it to stay level. (Originally designed for lighting in boats) I keep that one on my desk and light it regularly, using it as a desk light. It has an advertised burn time of about 50 hours on 11 oz of fuel. I've never timed mine, but that seems about right if the lamp is left turned down low using high quality fuel. More light than a candle, enough to comfortably read by, and being protected by a glass chimney, safer and easier to carry around for light.
I know it's terribly old school to turn to kerosene as lighting for an emergency, especially with LED lamps that burn into he hundreds of hours on a single set of batteries. But my lamps are part decoration, solid brass beauties; part testament to the quality workmanship of the past, these were the best/safest lamps available on boats and ships prior to the use of electricity; and finally I've found them to be ultra reliable.
I do have a couple candle lanterns around too, use them mostly when camping, but never have liked those for inside. The small bases seem more likely to be tipped and no good places to hang them. (In the middle of the room off the ceiling fan they are OK as a mood light, but other than keeping you from tripping over the recliner, not really enough light to do anything by.)
Like Gadgetgeek, I too like having multiple options. The thing is with a full bottle of kerosene in the cupboard, and my lanterns, lighting and some heat generation are possible for several weeks. (My larger lantern puts off a good amount of heat as is, and in an emergency could be Mcguyvered with a flower pot to give more.
