Lantern's Peace

Prevent mob spawning around soul light emitting blocks even if hidden underground.

Features:

You shall not spawn: No monster entities will be able to spawn inside a 16x16x16 rectangle around the soul light emitting block (or 8 blocks from each sides). Works even if the soul light source is placed hidden underground.

(in the gif the Soul Lantern is below the yellow concrete block to stops monsters spawning)
