Right, did some extensive testing with luminators now. (I have been using RP2 lamps because they look nicer and will turn off when you flick a switch but ran into other issues along the way that forced me to scrap the idea)
I also want my lighting to consume power. I don't like "free" stuff like torches and RP2's lamps. So luminators it is for that reason as well.
Now, the problem is that it's pretty expensive to set up luminators for tunnels that stretch for several hundred blocks underground. Having to use a whole bunch of transformers etc etc just to save on the energy loss in long cables.
It is possible to run them on tin wire from a bat box but you have to split the current and do all kinds of wonky things to get them to work on tin cable from any kind of generation/bat box besides solar panels. (which i WILL NOT USE, especially not in my underground mining shafts)
Somehow i was able to feed up to 28 EU/t down a tin cable after having experimented with adding and removing luminators and removing the split boxes.
But one small mistake and you would fry X number of tin cables in an instant. And setting them up is a PAIN. Plus (Not 100% sure) you can't remove a luminator and get it back...? (I have tried wrenching them, using my hands, drill and saw. They are destroyed when i break them)
The suggestion then is to introduce some kind of cable that will ONLY work with luminators and still can accept power from bat boxes/LV transformers without melting.
Maybe call it "thin copper wire" which you make out of 2 copper ingots and you get 16 of them?
It can be fed with LV (32 EU/t) and will only provide power to luminators. The energy loss could be 1 EU every 100 blocks (allowing you to hook up 32 luminators in 100 blocks or 1 luminator 3200 blocks away)
Any other ideas?
