Am trying to have some light coming out from my particles and i am using a geometry light

But i can't even see the reflection on the ground, i just have a little bit on my subject.

I've also tried to use a sphere and copy to points with my particles but the result is very unnoticeable.

Points need to be in a particle system primitive to be used with a geometry light. Use an ‘add’ node to create a particle system from points before feeding the geometry light. A sphere with copy to points should also work.
