First off, I can't say this is a bug, but I don't know where else to write this, so I'll be talking about it here.

For some reason when using the "light" block inside of Minecraft, it creates lag which is very confusing to me, "Why is a block that creates light lagging my game?" I am specifically using 126 blocks, which are in about a 100 block radius of each other. All of them are level 14. So with those specifics out of the way, why is an invisible light source block, with no particles, lagging my game? (If you know where I can relocate it to a better area or such, please let me know, I just don't know if this is the right spot)
