If you really don't want to carry around candles you can use crayons. Crayons when lit burn for a really long time. You can make an emergency torch by tying or duct taping some of these around the top of a stick. These have dual purposes get a coloring book for your kids while your camping for extra activity and for a torch at night if you need one. The best part is these are easy to carry and don't take up a lot of room.
