Add the White Lights post effect via the C4D render settings (post effects)

link a spline, particle or point object into the White Lights Object List

The first tick in this box enables or disables rendering for this item.
the second tick tells White Lights that the objects base color should be used instead of the color gradient.

once you have added the effect and inserted an object into the include list, you can render.

You can add some noise via the noise tab.

for something like this

NOTE: you can add multiple white lights to your scene and you can add the same object to  different white light effects.
