new beacon effects

I have seen others do beacon effects but none for what I think would be the most beneficial. Nigh vision beacons do sound very useful but to go a step further would give tears of joy to anyone whos had to light up huge areas. An effect that disables hostile mobs from spawning so the player can enjoy night without having to deal with ugly torches scattered across the ground and unauthorized Creeper explosions. its radius will be matched with the other beacon effects and to make a build 100% no light and no mobs a new block that "Absorbs" the beacons beam to make it not fire into the sky if the builder doesn't want it.
