This mod makes no change to lamps. Instead, Nauvis, Fulgora, Gleba & Aquilo are darker. Also, nightvision is green and glary... not particularly useful while toiling about in the safety of your base. All these things should further incentivize and help cultivate a love for lamps.
I used this mod on an existing save. How do I know if it is working? It doesn't seem any darker to me.
I couldn't find any settings, either. I looked in both the normal places. Does this mod have adjustable settings?

I forgot that I hid lamps behind major buildings in this save.
And I tuned them to the color of the heat pipes -- forgot about that too. My base had an inherent orange glow.
Can confirm the mod is working. Adjustable darkness would be nice.
