This page is about the Inverted Fixture from Project Red. For other uses, see Inverted Fixture.
The Inverted Fixtures are light sources added by Project Red. Inverted means that they don't need a redstone signal to illuminate. An incoming signal leads to turn off the Fixtures. The inverted version is the Fixture.
There are 16 colors for the Inverted Fixtures (see below).
The Inverted Fixtures 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.
