Issue description:

When placing disk drives next to each other they get darker the more you add them. I do not have optifine or any other lighting mod (except mods that add light sources) installed. I have also tested this with just the refined storage mod and the issue persists.

Steps to reproduce:

1. Place disk drives next/on top of each other

Version (make sure you are on the latest version before reporting):

• Minecraft: 1.15.2
• Forge: 31.1.41
• Refined Storage: 1.8.1

Does this issue occur on a server? [yes/no]

Yes.

Example of the issue outside setup:

This is a forge issue. An experimental version of the fix is in the latest version. Not sure if it needs any code changes to work

Update to the latest Forge and set "experimentalForgeLightPipelineEnabled = true" in the forge-client.toml config
