"Pow(d)er's in your hands" - Light sphere and particles - render tests

I don't post much of what i do mostly because of not having enough time,
but sometime i think it's nice to give it a shot and share some work,
Even if it's not the best quality out there some time it's nice to show different stuff, like reseaches !
These are some particle and light tests that acctually turned out not too bad,
I did my first particle system in 3dsmax with Tyflow and then tried the same in Blender.
I rendered the blender particles in two versions,
one version with "Octane" and the other with "cycles" to compare renders.
