I was searching for a method - a method that gives me glowing effects in cycles. May be it is possible in Internal Rendering but I wanted it for Cycles. I simply put glare node on the composition and I think I somewhat achieved what I want. I used despeckle node as well to get rid of unnecessary white dots on the bulb itself.
I used render passes in order to control emission seperately.
Nice idea to use DeSpeckle node to fix fireflies, good to clean up noise without re-rendering.
Cool little model!!
