The Lamp Post is a furniture item that can be used for decoration purposes or as a Light Source. The Lamp Post is 6 blocks high and 1 wide.
Placing a Bench beside the Lamp Post will help give your world a Park or City look. Lamp Posts give off the same amount of light as a Candle or Skull Lantern. It is not hindered by water, like torches which do not work at all, or glowsticks which wear out after a few minutes. Lava will make them pop out, if the lava is deeper than one block.
