As the title says, my cave Illuminator are generating light sources as far as 7 blocks above their Y-level. The book specifically states that they are generated below the Illuminator. So from my understanding if the Illuminator is at Y-level 73, then the max height the light sources can appear at would be Y-Level 72.
Them placing it above, means they are stopping my mob spawners, which i precisely placed above them, so that they would not be lit up by the Illuminator.

It was placing them on the floor of my spawner, before i put in the vector plates.
