About this Mod

This Mod adds a single Block: the Rainbow Lamp. It changes color dependent on its Redstone input, what makes it easy to display 16 states in a single Block. You can also right-click the Rainbow Lamp (while not sneaking) to cycle through all colors, if it isn't powered. Like the Vanilla Redstone Lamp, it also emits light unless it is in its black state.

Especially the right-click feature can certainly be used for decoration, but the Rainbow Lamp might also be interesting for Redstoners - think of a start signal for a racetrack or a working color display ...

Frequently Asked Questions

Rainbow Lamp server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.2). You can switch loaders with one click in the panel.

Is Rainbow Lamp compatible with fabric and forge and quilt?

Rainbow Lamp officially supports fabric, forge, quilt for Minecraft 1.20.2, 1.20.1, 1.20. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Rainbow Lamp – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Rainbow Lamp consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
