Which are the best lights for camping?
You'll probably want a variety of lights for camping. For use at the camp site, lanterns will be the best choice because they spread light over a large area. Each camper will want to have a flashlight for walks to the water fountain or restrooms. If you'll be doing any night hiking, you'll want a headlamp. If you'll be stargazing but want a flashlight to view a sky map, a blue or green LED flashlight will light up the map without taking away from the view.

Which flashlights should I have ready for emergencies?
A shake flashlight is great for emergencies, like earthquakes or hurricanes, because you won't need to worry about batteries; just shake the flashlight to increase the power reserve. If there is a long power outage, however, you may want the brighter light of a regular flashlight or even a lantern. To always be prepared, keep a rechargeable flashlight charged and ready.

Why are they called flashlights?
When flashlights were first invented in the late 19th century, the carbon filaments inside the bulbs weren't very reliable and would only work in brief flashes. The name stuck (at least in North America -- elsewhere, English-speakers call them "torches") even though advancements now let you keep flashlights on for much longer than just a flash.

What do I need to maintain my flashlight?
Flashlights are generally very durable, but there are a couple of things you'll want to think about in order to take care of yours. First, always have charged batteries on hand in order to make sure your flashlight always has plenty of energy. Second, if you don't plan to use your flashlight for a long period of time, take the batteries out to store it.
