Simply Light — Reference

Light Block & Fixture Types

Simply Light adds a small family of light sources, each suited to a different job:

Illuminant block - a full glowing cube in every colour. The workhorse of the mod: use it for floors, walls, ceilings, pillars, and hidden lighting. It gives off full brightness.
Illuminant slab - a half-height version of the block in the same colours. Great for thin glowing floors, steps, and low-profile ceiling lights where a full block is too tall.
Illuminant panel - a thin, flat glowing panel in the same colours. Ideal for backlit walls, glowing screens and signs, ceiling tiles, and slim accent surfaces.
Rod lamp - a slim standing light with a glowing head on a dark stem. Perfect for a single clean point of light on a table, counter, or post.
Tall lamp post - a taller standing lamp for lining paths, roads, gardens, and town squares with street-style lighting.
Light bulb - a small, compact light for interiors and detailed builds where a full block of light would be too much.
Wall fixture - a mounted light that sits neatly against a wall for entryways, hallways, and framed lighting.
Edge lights - thin light strips that run along the edges of blocks (covered in their own section below).

Every piece is a normal decorative block: place it, break it, and move it like any other building block.

Crafting & Getting Started

Everything in Simply Light is designed to be cheap and easy to make from common materials, so you can use it freely in survival as well as creative.

The blocks are crafted at a normal crafting table from inexpensive, easy-to-find ingredients - there are no special machines or multi-step processes.
Coloured variants are made the same way vanilla blocks are dyed: craft the base light and combine it with the matching dye (or craft it with that dye) to get the colour you want. You can recolour blocks by re-dyeing rather than starting over.
To see the exact recipe for any item, open your recipe book, or use a recipe-viewer mod such as JEI/EMI if you have one installed - just look up the block and the recipe will be shown.

Getting started:

Open the creative inventory and find the Simply Light tab to browse every block, slab, panel, fixture, and edge light the mod adds.
In survival, craft a base illuminant block, then dye it to your chosen colour.
Place a block where you want light - it glows immediately at full brightness.
Interact with a placed illuminant block to toggle it on or off.
Mix in slabs, panels, lamps, and edge lights to get exactly the look and light level you want.
