Martian Conduit Wall

It puts out a low light, enough to make a corridor readable but nowhere near a replacement for torches. Do not plan a build around it as a light source and then wonder why the room is dim.

The circuit pattern on it lines up with Luminite Brick Wall, so the two tile into each other without a break in the design. That is the pairing worth building around for a late game tech base. The plating comes out of Martian Madness and the Luminite after Moon Lord, so by the time you are decorating you will have piles of both.
