Modern Lights
by aka_Jammy
Modern Lights adds a set of light blocks, slabs and mini blocks for building lit interiors, exteriors and decorative lighting on Fabric.
What it does
The mod supplies simple light blocks with a modern look, along with two slab variants and a single full block. Crafting a pair of vertical slabs returns the matching full block, and the stonecutter turns a light block into a slab or a mini block. Recipes were repaired and a few new ones were added, and the Luminous Block recipe was made more expensive on purpose.
Fabric API must be installed on the same loader, since Modern Lights depends on it. A server running it needs every connecting player to have it too. Files are published for Fabric across 23 release versions, 1.16.5 – 1.21.4, and the latest file is 2.5.0 for 1.21.4, released 2025-06-17, under the Creative Commons Attribution Non Commercial Share Alike 4.0 license. The mod is not open source, though its source code and issue tracker are public.
Key features
Light block set
Light blocks in several shapes, including slabs, a full block and mini blocks, for lighting building projects.
Stonecutter output
The stonecutter converts the light blocks into slabs and mini blocks, which makes shaping a lit build faster.
Vertical slab crafting
Crafting two vertical slabs gives back the corresponding full block, so partial pieces can be recombined.
Repaired recipes and advancements
Broken recipes and advancements were fixed, and several new recipes were added to round out the set.
