Emissive Light - Not Emitting

I made a quad in Unity and applied a Standard material with a white albedo and a white emissive.

It glows but does not emit light onto other objects. The emitter and the objects are all set to static. The weird thing is, when I apply the emissive material to some of the static objects (.fbx objects) I am trying to light, it works. What could I be missing?

Also as a general question, what are the pros and cons of an emissive light compared to a spot or a point light?

Thanks.

Currently spot and point light do not work with the realtime GI system.
So your only way to dynamically update your realtime GI is with static meshes and emissive materials set to realtime GI.
Keep in mind that dynamic objects are only lit via light probes.
Make sure that your realtime GI is backed in order to have it all work.
