I’m sorry. Difficult to use means that there are few things you can just place like a torch. The only ones that can be used are Glow Glass, Greg O’lantern, and ZPM. Others need to be prepared for use as a light source, such as needing to be water, not being able to be placed in the air, or needing a red stone signal.
If you want a nice looking lamp, just use another mod, but I don’t want to put in another mod as much as possible, so I want a lamp prepared by Gregtech.
Glowing floors and walls are useful, but a factory with glowing floors and walls is a bit disconcerting. (This is just my personal preference).
