Mekanism: Mekalights
by MrPochy
Players who build large Mekanism bases need light that does not clutter the space, and MekaLights supplies five light shapes fed by Mekanism power.
What it does
MekaLights adds one block that floods an area with invisible, full-brightness light emitters, reaching up to a 48-block radius from a single placement. Torches stop being needed in caves, factories and farms because the light covers the same ground without leaving blocks on the floor or walls.
The block accepts Mekanism power and is configured from a side panel in a Mekanism-style interface. The panel shows the chosen shape, range, brightness and aperture, along with a live energy readout. Jade is required on both client and server, and the mod needs Mekanism as a dependency. The files cover Forge and NeoForge across 7 release versions, and the code is covered by All rights reserved, so the mod is not open source.
Key features
Five light shapes
Sphere, disc, cone, dome and cylinder each cover a different kind of space, from full 3D volumes to flat floors.
Adjustable brightness and aperture
A dial sets light intensity from dim to full, and the cone and dome apertures run from 15° to 90° with six aimable directions.
Cylinder height control
The cylinder shape has an adjustable column height from 4 to 32 blocks.
Live side panel
The GUI shows shape, direction, range, brightness and aperture with pixel icons, plus a live energy readout.

Use cases
Cave and big room lighting
The sphere shape fills caves and large rooms in full 3D, so one block replaces many torches.
Mob-proofing floors
The disc shape lights a flat layer across floors and fields, which helps keep hostile mobs from spawning there.
Who it’s for: Players and server owners running industrial-scale Mekanism bases who want lighting that stays out of the way.
How it compares
Mekanism Lights is another lighting option for the same versions, with Forge and NeoForge files, but it is not open source. Mekanism Covers is open source under the Mozilla Public License 2.0 and covers the same loaders, which suits a different part of a base.
