This effect trys to simulate the photographic problem of 'blooming', where areas of a picture exposed to very strong sources of light bleed into neighbouring areas, brightening them and giving light sources a 'halo'.
Parameters

1. Radius
This controls how widely the brightening effect extends away from the light source, the larger the value the more area it covers
2. Passes
If you turn this down to 1 or 2 you'll get better performance but you get a blockier look. With the default value of 3, you get much more rounded halos.
3. Floor
This parameter specifies the lowest brightness that you need before a halo is generated.
4. Ceiling
This sets the brightness value where the halo is at its maximum strength.
5. Aspect Ratio
This changes the shape of the halo, from stretched out horizontally, to circular, to stretched vertically
