This page is about the Cage Lamps from Project Red. For other uses, see Cage Lamp.
The Cage Lamps are light sources added by Project Red. They need a redstone signal from red alloy cables, redstone, an adjacent circuit or other blocks/machines which emits a redstone signal to illuminate. The inverted version is the Inverted Cage Lamp.
There are 16 colors for the Cage Lamps (see below).
The Cage Lamps form a quadratic cone of light and the luminosity amounts to 14 spaces straight in all 4 directions from the block. However, the light is so strong that no mobs spawn only up to a distance of 7 blocks.
