Black Lightning Effect

Hello guys, I am looking for a solution for something I wanted to create for quite some time.
The thing I want to do is basically make a very dark/black object emit light, so it creates this sort of corrupt energy effect. What I am doing right now is not satisfactory, cause it's a workaround really and it doesn't end up the way I really want it to. ATM the closest I came to doing so I making a white outline that emits light while leaving the core of texture black. It doesn't look too good as the light affects the black pretty significantly.


What would work is if the texture completely covered the light. And it needs to be applicable in particle system If anyone knows a way to approach it it would be dope. Thanks!
