"Add Light" / Invisable Light

This is badly needed my spawn town keeps having trillions of animals and monsters showing up and I don’t want to throw a ton of torches or lamps all over it, I just want it to have light without the visual stuff that goes along with that. Please can someone make this for 1.12.2?

You could use a plugin like GriefPrevention, and set flags for the Town area that prevent spawning.

Yeah I been trying to figure out how to do that too but I’m still very new to using all these commands and mods I’ll have to look that up tommorow thank you for the advice
