Calibrated Redstone Lamp
by coolhouse_82
Calibrated Redstone Lamp is a Fabric block mod in which a lamp changes its colour according to the redstone signal strength entering it.
What it does
The lamp reads the total redstone power that reaches it and shows that value as one of sixteen colours, from black at signal 0 through grey, brown, red, orange, yellow, lime, green, cyan, light blue, dark blue, purple, magenta and pink at signal 15. A comparator can read the current status of the lamp, so a build can check which level is active.
Amethyst crystals are used to dope the lamp, which the author describes as a way to bend light and gain a different colour response. Players may also use the mod in farm mini games, where the colour gives a visible readout of a circuit. Calibrated Redstone Lamp is published for Fabric and runs on 26.1.2 only.
A server running it needs every connecting player to have it too. The license is CC0 1.0 Universal, a public domain dedication, and the mod is not open source in the sense of a public code repository. Files were first published and last updated on 2026-08-31, and the Fabric file is 1.0.0-26.1.2 for 26.1.2.
Key features
Signal-strength colours
The lamp shows sixteen colours, one for each redstone signal level from 0 to 15.
Amethyst doping
Amethyst crystals alter the lamp so its colour response to incoming signal changes.
Comparator readout
A comparator placed next to the lamp reads its current status, letting circuits respond to the colour level.
Farm mini games
The coloured signal output suits farm mini games that need a visible level indicator.

Use cases
Signal readouts
A build can show the strength of a redstone line at a glance, since each signal level has its own colour.
Decorative circuits
Lamps can be placed as lighting or display elements that change colour with the circuit driving them.
Who it’s for: Redstone builders who want a lamp that displays signal strength, and server owners running mini games that rely on visible circuit states on 26.1.2.

What the author says
Block state changes depending on total redstone power entering it. The calibrated lamp uses the refractivity of amethyst crystals to change the color of the lamp depending on the strength of the redstone signal. Use it in farm, mini games and more. Here are the colours the lamp can be: Signal 0: Turned off and…
