Reactorcraft:
radioluminescent lamps.
Now, hear me out on this.
- Reactorcraft has several different colors of fluorite
- Reactorcraft fluorite radioluminesces
- Reactorcraft has tritium
- Tritium and a radioluminescent material are often used together to make long-lasting, self-powered lights
The idea would be to introduce lamps, perhaps crafted with some blast glass, steel and a block of fluorite, that could then be placed in a fueling station and filled with tritium. This would produce a powerful light source, ideally filling roughly the same purpose as Factorization Wrathlamps and Thaumcraft Arcane Lamps, but less broken (and inaccessible in 1.7) and more techy respectively. Also available in 9-or-so separate colors.
