Nodecore provides a few light sources by default, sure, but they are not that useful: torches burn out quickly, and optics systems are hard to set up and are not that extendable. The lanterns in this mod provide reliable on-the-go lighting without being overpowered, since they require quite a bit of materials to make and fuel to operate. That said, they do make underground mining easier, so if that's a part of nodecore you wish to preserve that way don't use this mod. Also, hints should be added through the Nodecore's hint system for how to make the lanterns.
