Glow or Halo for Lights like BloomAndLensFlares shader?

Hi, I need a shader that creates a glow around lights like the BloomAndLensFlares shader that I am currently using but it's to expensive and takes 1ms on my gpu at 1080p.

Any suggestion?

 

You can modify the existing light halo shader, as described here: http://docs.unity3d.com/Manual/class-Halo.html
