About What’s My Light Level Mod:

This simple mod makes the game display the light level of the current block you’re standing on in the top left corner of the game screen. Very handy to see if your base is lit enough, or if your trees and/or crops can grow, it can even help you if you’re trying to make an animal or mob farm!


Checking the light level.

Checking if anything can grow or spawn here.

Checking on how well the game’s performing.

Checking our coordinates and what biome we’re currently in.

Checking the world seed so our friends can play this world, too!
