The B<dura> line of lanterns have enhanced burning duration. This is achieved by them having a much larger tank. It will give you enough light for at over half a month of continuous adventuring. There is a saying that claims: "if you can lift a dura once, you won't put it down again." This bright dura model gives as much light as a normal bright lantern. H<Half a month in game is around one day in real time. You can only light it up with flint & steel.>
