I have a little problem with this property.
I would simulate a neon light using “emission”, but with a gameobject static and emission 60, i don’t have a light effect, only a white color…
Sorry if i don’t write other but in tutorial and in documentation is very easy 
I use unity 5.0.0f4
Please provide some more context. Like which material are you using (custom shader?)
Maybe the color gets saturated to white… How does it look with intensity set to 2?
Is your environment lightmap static? Is lighting turned on?
Can you post a screenshot?
Ok, in this time i have upgrade unity to 5.1.1f1
The lightmap of gameobject is static.
I had created a new material, the shader is standard and i set color and valor of the emissive.
Then i added this material. The gameobject is become white but self-light effect doesn’t work.
I tried set emissive value from 1-2 to 1000, and emissive color white, grey, red and other color.
(Sry for my debatable english)
Now some screenshot:
Ok, i tried use lighting demo that i downloaded from asset store, this is a screen.
I don’t know reason.
It looks like your lighting is static and your emission is set to realtime. Try setting baked emission.
