So I was thinking if there was a way to kill mobs (specially creepers near storage sorting system, nuclear reactors and such) without using the dangerous and power hungry teslas or also dangerous and power not-so-hungry uninsulated cables.
If I'm not mistaken Luminators can kill those mobs and are a good and pretty light source (even better with cfed cables).
So what I need, and couldn't find, is a way to convert LV (32 EU/t) to 5 EU/t. That way it would be possible to use tin cables to transfer the low energy required by luminators with low energy loss and low price cable.
If not I think it would be doable to use copper cables with bat-box every 5 or so blocks.
