NightLantern does what it says, its a Lantern that works when its night. You place it down and when the sun is setting and mobs just about to start spawning it light up telling you that its now night, or that its okey to sleep. The model of the big lantern might change in a update, I had a few different models but I wanted to release the mod I removed them. And the big one was made quick just to have something that might fit villages. Since they are tile-entities they do cause lag if there are a bunch placed, and since they update the light it too might spark a lag spike when they all update at the same time.
