Modern Lights
by Sythatic
Modern Lights adds a set of chromatic light blocks in several shapes, including full blocks, slabs, vertical slabs and mini blocks, for decorative lighting builds.
What it does
The mod introduces new luminous blocks that come in colored, chromatic variants. Each shape has a regular and a full version, so a builder can light a wall, floor or ceiling with slabs, vertical slabs or small mini blocks instead of whole cubes. An Andesite Frame block is included as a decorative piece to set alongside the light blocks.
Modern Lights requires Fabric API and runs on Fabric only, with files for 1.21 and 1.21.1. Both the server and every player need the mod, because the client and server environment applies. The license is Creative Commons Attribution Non Commercial Share Alike 4.0, so the project is not open source. The latest file is 3.0.0-beta1 for 1.21.1, a beta build published on 2024-11-04.
Key features
Chromatic light blocks
Light blocks in several colors give builders a palette for lit interiors, signs and street scenes.
Full and slab shapes
Full blocks, slabs and vertical slabs each come in a regular and a full variant, so light fits the shape of a build.
Mini luminous blocks
Small luminous blocks add light to tight spaces where a full block would not fit the design.
Andesite Frame
A frame block made of andesite pairs with the luminous blocks as a decorative trim piece.

Use cases
Lighting builds
Builders use the slabs and mini blocks to place light at edges, under ledges and inside corners of a structure.
Themed interiors
The colored variants let a player match lighting to a room's color scheme.
Who it’s for: Players who build decorative spaces in survival or creative worlds on Fabric 1.21 or 1.21.1, and server owners who want shared lighting blocks available to every player.
How it compares
Vertical slabs by Misterxycb is a Fabric, client and server mod for 1.21 – 1.21.1, under All rights reserved and not open source, so it covers vertical slabs without luminous variants. Luminous Blocks is a multi-loader mod on Fabric, Forge and NeoForge for 1.20.1 – 1.21.6 under a custom license and is not open source, which gives it a wider version range than Modern Lights. Slabee is open source under the MIT License and targets only 1.21.1 on Fabric.
